Answer:

B

Explanation:

The impulse experienced by an object is the force•time.

The correct answer is D. Amount of time and area of physical contact between the substances.

Explanation:

Heat transfer refers to the flow of thermal energy or heat between two or more objects. This process involves multiple factors and implies heat from the hottest object goes to the coldest one until there is an equilibrium. To begin, heat transfer depends on the amount of thermal energy in the objects because objects must have a different amount of thermal energy for heat to flow.

Besides this, the amount of energy that flows depends on the time and the contact between the substances of objects. Indeed, objects need to be in contact or close to each other for heat to transfer, and the time needs to be enough for the process to occur. For example, if you place a pot over the fire just for a few seconds it is likely the heat transferred is minimal, which does not occur if you leave the pot more time. At the same time if the pot is in close contact with fire more heat will be transferred.-

Body protein as well as other vital nitrogen-containing substances including creatine, peptide hormones, as well as some neurotransmitters cannot be produced without amino acids. Although limits are expressed in terms of protein, amino acids are a biological necessity.

Amino acids are the primary building elements of proteins. Their molecule has both an amino as well as a carboxylic group. Alpha-amino acid are amino acids that have a carboxyl group and an alpha-carbon atom linked to the same carbon atom. Glycine, alanine, etc. are a few examples.

The moment of inertia, denoted as I, is the measure of an object's resistance to rotational acceleration. It depends on the shape, mass distribution, and orientation of the object. For a thin, uniform disk rotating around its center of mass, the moment of inertia can be calculated using the formula Icm = (1/2)mr^2, where m is the mass of the disk and r is the radius of the disk.

The moment of inertia of a thin, uniform disk rotating around its center of mass is given by the formula Icm = (1/2)mr^2, where m is the mass of the disk and r is the radius of the disk.

Answer:

The star's luminosity rises above its previous level. Because it is so cool, the surface will be red, and it will be much farther away from the center than it was during the earlier stages of star evolution. Despite its lower surface temperature, the red giant has a large surface area, which makes it very luminous.

Coulomb's law is express as:

The length of the string is 2.75m and the frequency of the pendulum is 0.2Hz.

Frequency is a measure of the number of cycles of a periodic wave that occur in a unit of time. It is usually expressed in Hertz (Hz), which is the number of cycles per second. The frequency of a wave determines its perceived pitch, with higher frequencies producing higher pitches and lower frequencies producing lower pitches.

a. The length of the pendulum required to achieve a period of 5 seconds can be calculated using the formula:

T = 2 * π * √(l/g)

where T is the period, l is the length of the pendulum, and g is the acceleration due to gravity (approximately \(9.8 m/s^2\)). Solving for l:

\(l = (g * T^2) / (4 * π^2)\)

Substituting T = 5 seconds and g =\(9.8 m/s^2\), we get:

\(l = (9.8 * 5^2) / (4 * π^2)\) = 2.75 meters

So the correct answer is c. 2.75 meters.

(22) b. The frequency of a pendulum is given by the formula:

f = 1 / T

where f is the frequency and T is the period. Substituting T = 5 seconds, we get:

f = 1 / 5 = 0.2 Hz

So the correct answer is d. 0.2 Hz.

Therefore, The length of the string is 2.75m and the frequency of the pendulum is 0.2Hz.

Answer:

The body flies off to the left at 9.1 m/s

Explanation:

Law Of Conservation Of Linear Momentum

It states the total momentum of a system of bodies is conserved unless an external force is applied to it. The formula for the momentum of a body with mass m and speed v is  

P=mv.  

If we have a system of bodies, then the total momentum is the sum of the individual momentums:

\(P=m_1v_1+m_2v_2+...+m_nv_n\)

If a collision occurs and the velocities change to v', the final momentum is:

\(P'=m_1v'_1+m_2v'_2+...+m_nv'_n\)

Since the total momentum is conserved, then:

P = P'

In a system of two masses, the equation simplifies to:

\(m_1v_1+m_2v_2=m_1v'_1+m_2v'_2\qquad\qquad[1]\)

Wall-E robot is initially at rest, its two parts together. His head has a mass of m1=0.75 kg and his body has a mass of m2=6.2 kg. Both parts have initial speeds of zero v1=v2=0.

After the explosion, his head flies off to the right at v1'=75 m/s. We are required to find the speed of his body v2'. Solving [1] for v2':

\(\displaystyle v'_2=\frac{m_1v_1+m_2v_2-m_1v'_1}{m_2}\)

Substituting values:

\(\displaystyle v'_2=\frac{0.75*0+6.2*0-0.75*75}{6.2}\)

\(\displaystyle v'_2=-9.1 \ m/s\)

The body flies off to the left at 9.1 m/s

The focal length in the case of a concave mirror refers to the distance between the mirror's vertex and its focal point.  it is considered negative because the focal point is located on the same side as the incoming light rays

The focal point is where parallel rays of light converge after reflecting off the mirror's concave surface. In a concave mirror, the focal length is considered negative. This is because the focal point is located on the same side as the incoming light rays, which is the reflective (concave) side of the mirror.

The sign convention for focal length is based on the Cartesian coordinate system. A positive focal length corresponds to a convex mirror, where the focal point is on the opposite side of the mirror from the incoming light rays. In contrast, a concave mirror has a negative focal length due to the focal point being on the same side as the incoming light rays.

To summarize, the focal length in a concave mirror is the distance from the vertex to the focal point, and it is considered negative because the focal point is located on the same side as the incoming light rays, which is the reflective (concave) side of the mirror. This sign convention helps distinguish between concave and convex mirrors in optics and related calculations.

0.2

Explanation:

The given parameters are;

The acceleration of the train, a = 0.2·g

The mass of the person standing on the train = m

Let μ represent the coefficient of static friction, we have;

The force acting on the person, F = m × a = m × 0.2·g

The force of friction acting between the feet and the floor, \(F_f\) = m·g·μ

For the person not to slide we have;

The force acting on the person = The force of friction acting between the feet and the floor

F = \(F_f\)

∴ m × 0.2·g = m·g·μ

From which we get;

0.2 = μ

The coefficient of static friction that must exist between the feet and the floor if the person is not to slide, μ = 0.2.

Given, the mass of the sample = 433 kg. We need to find the mass of the sample in milligrams (mg).

1 kilogram (kg) = 1,000,000 milligrams (mg)

Therefore,

Mass of the sample in mg = 433 × 1,000,000 mg = 4.33 × 10^8 mg.Hence, the answer is an option (e) 4.33 × 10^8 mg.

The conversion factor between kilograms and milligrams is 1 kg = 1,000,000 mg. Therefore, to convert the mass of the sample from kilograms to milligrams, we simply multiply it by 1,000,000.

433 kg × 1,000,000 mg/kg = 433,000,000 mg

To express the result in scientific notation, we write it as 4.33 × 10^8 mg.

Answer:

b) The gravitational pull will be weak.

Explanation:

Less mass requires less force. Gravity or gravitational pull is a force. In order for you to stay in place and not go through the ground, however, you require something to pulling you away from the Earth. That's why we have air resistance.

Given :

Mass of block , m = 1.35 kg .

Speed constant , k = 15 N/m .

Speed at centre , v = 34 cm/s = 0.34 m/s .

To Find :

The amplitude of oscillation .

Solution :

Now , we know total energy is conserved in SHM .

So , K.E at zero displacement :

\(K.E=\dfrac{mv^2}{2}\\\\K.E=\dfrac{1.35\times 0.34^2}{2}\\\\K.E=7.8\times 10^{-2}\ J\)

Now , this K.E is equal to maximum P.E :

\(P.E=K.E=7.8\times 10^{-2}\ J\) .

\(P.E=\dfrac{kA^2}{2}\\\\7.8\times 10^{-2}=\dfrac{kA^2}{2}\\\\A=\sqrt{\dfrac{2\times 7.8 \times 10^{-2}}{15}}\ m\\\\A=0.1019 \ m\\\\A=10.2\ cm\)

Therefore , the amplitude is 10.2 cm .

Hence , this is the required solution .
