4 m/s in negative acceleration

Explanation:

Acceleration = V- U/t

Where V is the final velocity

U is the initial velocity and t is the time given.

U = 65 m/s

V= 25 m/s

T= 10 seconds

Acceleration= (25m/s - 65m/s)÷10secs

= - 40/10

= -4m/s^2

Hence, it has a negative acceleration.

Answer:

A. negative acceleration of 4 m/s2

On average, it can take approximately 1-2 hours of continuous moderate to high-intensity aerobic exercise to deplete muscle glycogen stores.

The time required for muscle glycogen to become depleted during aerobic exercise varies depending on factors such as exercise intensity, duration, and an individual's fitness level.

During aerobic exercise, muscles primarily rely on glycogen, which is a stored form of glucose, as a source of energy. The rate at which muscle glycogen is depleted depends on several factors. Higher exercise intensity and longer duration lead to faster glycogen depletion. Additionally, an individual's fitness level and glycogen storage capacity can influence the depletion time.

On average, it takes approximately 1-2 hours of continuous moderate to high-intensity aerobic exercise to deplete muscle glycogen stores. However, it's important to note that individual variations exist, and some athletes with well-trained muscles and higher glycogen stores may sustain glycogen levels for longer periods, while others may deplete their glycogen stores more quickly. Factors like nutrition, pre-exercise glycogen levels, and the presence of carbohydrate supplementation during exercise can also affect the rate of glycogen depletion.

Work is said to be done when a force applied to an object moves that object. We can calculate work by multiplying the force by the movement of the object.

Answer:

Work is done by a force on an object if (i) a force acts on the object and (ii) the object is displaced from its original position

A sharp point needle pierce easily than a blunt edge​, because of high pressure of needle. Pressure is nothing but the force per unit area. in he needle there is force applied on very small area therefore it has high pressure applied on the area. whereas, blunt edge has large area for equal force, that is why.

Pressure is defined as the force applied perpendicular to an object's surface per unit area across which that force is dispersed. Gauge pressure is the pressure in relation to the surrounding atmosphere. Pressure is expressed using a variety of units.

Identification of compounds can benefit from density. It is also a useful feature since it connects (or acts as a conversion factor between) a substance's mass and volume. Volume and mass are extended (or extrinsic) qualities of matter that are quantity dependent.

The force of an air mass acting on the earth's surface is known as atmospheric pressure. Remember that wind currents are created when the densities of two separate air masses differ.

Our wind currents are driven by the atmospheric pressure density, and denser air exerts a higher pressure than less dense air. Compared to the cold and dry air, the warm and humid air is less dense. The less dense air will then float on top of the thicker air in certain regions.

Therefore, Warm air masses rise while cold air masses descend because they are less dense.

Answer:DOWN a Group: Atomic radius INCREASES as you go DOWN a Group because each successive Period (row) has an additional occupied energy level. If you visualize the not 100% accurate but still useful Bohr model of the atom, you can think of it this way: each time you drop down a row, you add a "ring." ACROSS a Period: Atomic radius DECREASES as you go ACROSS a Period because the net nuclear charge increases (Huh?). Remember, it's the protons (+) in the nucleus that pull on or attract the electrons in the orbitals. Across a Period you are adding more and more protons pulling on electrons occupying the same orbitals. The overall effect is more pulling power in the same basic space. This draws the electrons in closer, making the overall atomic radius smaller at the right side of a Period.

Ionization Energy:

DOWN a Group: Ionization energy DECREASES as you go DOWN a Group because the farther the valence electrons are from the nucleus (pulling power of the protons) the less energy it costs another atom to steal them. ACROSS a Period: Ionization energy INCREASES as you go ACROSS a Period because atoms are getting ever closer to that magic "octet" rule for stability via the Noble Gas configuration. In plain speak - your frequent buyer punch card gets one step closer to the freebie each time you move closer to the right of the Periodic Table so you guard those punches more carefully. The atomic radius is getting smaller, too, so those protons do a great job of holding on tighter.

Electron Affinity:

Electron affinity is a bit outside the scope of this class so I'm not going to get into it too deeply, other than to point out the general trend.

DOWN a Group: Electron Affinity DECREASES (a tiny bit) as you go DOWN a Group because elements become slightly less attractive toward electrons. Father from the pull of those protons, remember?  ACROSS a Period: Electron Affinity INCREASES as you go ACROSS a Period because generally speaking (and remember, exclude the Noble Gases here) elements toward the right of the Periodic Table give off a great deal of energy when they gaining electrons to become more stable.

Electronegativity:

DOWN a Group: Electronegativity DECREASES as you go DOWN a Group because the valence electrons are increasingly farther away from the attraction of the protons in the nucleus. Less pull, less "desire" to grab other electrons. ACROSS a Period: Electronegativity INCREASES as you go ACROSS a Period because the number of protons (+ charges) in the nucleus increases. More protons in the nucleus means electrons are more strongly attracted to the nucleus.

Chemical Reactivity:

METALS

DOWN a Group: In METALS reactivity INCREASES as you go DOWN a Group because the farther down a Group of metals you go, the easier it is for electrons to be given or taken away, resulting in higher reactivity. ACROSS a Period: In METALS reactivity DECREASES as you go ACROSS a Period because though they still want to give away valence electrons they have more of them to get rid of, which requires more energy. Not as easy to blow off a little steam!

Explanation:

If a system absorbs 12 J of heat from the surroundings; meanwhile, 28 of work is done by the system then the change in internal energy is 40 J. The correct answer is (d) 40 J

The first law of thermodynamics states that the change in the internal energy of a system is equal to the heat added to the system minus the work done by the system. Therefore, ΔU = Q - W.
In this case, the system absorbs 12 J of heat from the surroundings, which means Q = 12 J (note that we use a positive sign because heat is added to the system). Additionally, 28 J of work is done BY the system, which means W = -28 J (note that we use a negative sign because work is done BY the system).
Now we can calculate the change in internal energy:
ΔU = Q - W = 12 J - (-28 J) = 12 J + 28 J = 40 J
Therefore, the answer is (d) 40 J.

2. The food supply is bound to spoil on Mars since it would be stored unrefrigerated. This is as a result of the actions of the micro organisms acting on them.

For the criteria for the engineering design problem:

1. The distance between earth and Mars is very far

2. Not factoring in the preservation method into the unmanned aircraft.

Explanation:

During the resting phase, the electric potential energy of a typical Na+ ion outside of the cell is higher than inside the cell.

The resting membrane potential is the difference in electric potential between the inside and outside of a cell when the cell is at rest. This potential difference is maintained by the activity of ion channels and ion pumps in the cell membrane. The resting membrane potential of most cells is negative inside with respect to the outside.

For a typical neuron, the resting potential is around -70 mV, which means that the inside of the cell is negatively charged relative to the outside. This difference in charge creates an electric field that can do work on ions that move across the membrane.

In the case of a Na+ ion, the electric potential energy is higher outside the cell because the outside of the cell is more positively charged relative to the inside. This creates an electrochemical gradient that tends to drive Na+ ions into the cell.

Jill caught up to Jack after 4 seconds.

Jack had a head start of 10 yards in the uphill race. However, Jill was running uphill at a faster rate of 5 yards per second. This means Jill was gaining on Jack by 5 yards every second.

Meanwhile, Jack was falling behind at a rate of 2 yards per second. This means he was losing distance to Jill at a rate of 2 yards every second.

To determine when Jill caught up to Jack, we need to find the time it takes for Jill to cover the initial 10-yard head start plus the additional distance Jack falls behind.

Distance gained by Jill = Head start + Distance Jack falls behind

Distance gained by Jill = 10 yards + (2 yards/second × t seconds) [where t is the time in seconds]

Jill's distance covered = Rate of Jill × Time

Jill's distance covered = 5 yards/second × t seconds

Setting the two distances equal and solving for t:

10 yards + 2 yards/second × t seconds = 5 yards/second × t seconds

Simplifying the equation:

10 + 2t = 5t

10 = 3t

t = 10/3 ≈ 3.33 seconds

The angle with the point (-6,-5) on its terminal arm can be determined by calculating the arctan of the ratio of the y-coordinate to the x-coordinate. The value of the angle is approximately -137.4 degrees.

To find the value of angle a, we can use the arctan function, which gives the angle whose tangent is a given number. In this case, the tangent of angle a is equal to the ratio of the y-coordinate to the x-coordinate of the given point (-6,-5). We can calculate this ratio as follows: tan(a) = (-5)/(-6) = 5/6.

Next, we need to find the angle whose tangent is 5/6. We can use the inverse tangent function (arctan) to determine this angle. Using a calculator or a trigonometric table, we find that arctan(5/6) is approximately 38.66 degrees.

However, this angle is in the first quadrant, and we need to find the angle in standard position. Since the point (-6,-5) lies in the third quadrant (negative x and negative y values), we need to add 180 degrees to the angle found. 38.66 + 180 = 218.66 degrees.

Finally, to the nearest tenth degree, the value of angle a is approximately -137.4 degrees (360 - 218.66).

It is frequently stated that the value of the acceleration due to gravity at the pole is larger than at the equator because the poles are closer to the center of the earth due to the earth's oblateness. ... The measured value is larger because the earth's density is not uniform but increases toward the center.

Answer:

as explained that poles have more gravitational

force (9.83m/s^2) as the poles of earth is nearer to the center because it is flat at poles

but certainly at equator is having less gravitational force (9.78m/s^2) as it is Farr from centre of earth because it is bulgded at equator.
