1. Examine your data table closely. Notice that the Average Applied Force and Average Net Force are different. Explain why these average forces differ.
2. Why should average net force be used to determine the acceleration of the apparatus? Explain.
Please help!!!
Answers
Here we can't see the difference between average applied force and average net force.
Sadly, we can't see the tables, but we can answer in a general form.
1) We define average applied force as a force that we apply on a given object.
For example, if we have a box on the ground and we push it horizontally with 50N of force, the average force applied will be 50N.
While average net force refers to the sum of all the forces applied in the box.
Let's return to the previous example.
Now assume that you do not push the box exactly horizontally, but there is a slight angle upwards.
Then there will be a component of the force that is horizontal and a component that is vertical, and is likely that the vertical component of the force is canceled by the weight (also a force) of the box.
Thus the applied force can still be equal to 50N, but the net force may be a little bit smaller.
This is why these average forces differ.
2) Why should the average net force be used to get the acceleration?.
Again, if some part of the applied force is canceled (by the weight or another force) then that force does not affect the object in any way. This is why we need to use the average net force to compute the acceleration.

The density of the gas in the tank would increase.
C.
The size of the gas particles in the tank would increase.
D.

Answer:
Its A
Explanation:
Because the pressure exerted by the gas in the tank would increase.
The statement that predicts what would happen if the scuba tank were to increase in temperature is that pressure exerted by the gas in the tank would increase.
What is the relationship between pressure and temperature?The pressure and temperature of a gas in a container is connected by the pressure law equation, which states as follows:
P1/T1 = P2/T2
This equation depicts that an increase in the pressure of a gas also increases the temperature.
Therefore, the statement that predicts what would happen if the scuba tank were to increase in temperature is that pressure exerted by the gas in the tank would increase.

when the angle of inclination of the inclined plane increases, what will happen to the acceleration along the inclined plane?
Answers
When there is acceleration along the inclined plane then accelerations increase as incline angles increase.
angle of inclination :
The angle between a line's inclination and the x-positive axis's direction is known as the inclination.This angle's value ranges from 0° to 180°.It is measured counterclockwise around the positive x-axis direction.The force component parallel to the incline rises as the angle increases, while the force component perpendicular to the incline falls. The acceleration is brought on by the parallel portion of the weight vector.
Therefore, accelerations increase as incline angles increase.
When there is acceleration along the inclined plane then accelerations increase as incline angles increase.

What is the acceleration of a car initially traveling at -5m/s and
reaching -22m/s in 3s.
Answers
Answer:
\(a=-5.67\ m/s^2\)
Explanation:
Given that,
Initial velocity, u = -5 m/s
Final velocity, v = -22 m/s
Time, t = 3s
We need to find the acceleration of the car. The formula of it is given by :
Acceleration,
\(a=\dfrac{v-u}{t}\\\\a=\dfrac{(-22)-(-5)}{3}\\\\a=-5.67\ m/s^2\)
So, the acceleration of the car is \(-5.67\ m/s^2\).

A 160 kg cart has a momentum of 870 kg m/s. What is the velocity of the cart?
Answers
Answer: 5.44 m/s
Explanation:
Given:
Mass of cart: 160 kg
Momentum of cart: 870 kg•m/s
\($$Momentum $|\rho|=m \times v$$$\begin{aligned}&870 \ kg\cdot m/s=160 \mathrm{~kg} \times v \\&v=5.44 \mathrm{~m} / \mathrm{s}\end{aligned}$$\)
Answer:
The momentum is defined as :
P=mv
Where m is the mass and v is the velocity. In this case we know the mass is 160 kg and the momentum is 870 kg plugging in this equation above and solving for the velocity we have
870=160V
V=870÷160
V=5.44
Therefore, the velocity of the cart is 5.44 m/s.
A sample of polonium-210 was left for 414 days.

The half-life of polonium-210 is 138 days.
Calculate the initial mass of the sample

Answer:
PO(1) = PO(0) / 2 1 refers to 1 half life of PO(0)
PO(2) = PO(1) / 2 = P(0) / 4 amount of PO left after 2 half-lives
PO(3) = PO(2) / 2 = PO(0) / 8 amount of PO left after 3 half-lives
414 da / 138 da = 3 3 half-lives pass in 414 da
PO(0) = 8 PO(3) = 8 * 1.45E-4 g = 1.16E-3 g = .00116 g after 414 days

3.) using calories, calculate the how much heat 32.0 g of water absorbs when it is heated from 25.0oc to 80.0oc. how many joules is this?
Answers
The specific heat capacity of water is 1 calorie per gram per degree Celsius. This means that 1 gram of water will absorb 1 calorie of heat for every 1 degree Celsius increase in temperature.
In this case, we have 32.0 grams of water that is heated from 25.0 degrees Celsius to 80.0 degrees Celsius. The change in temperature is therefore 80.0 - 25.0 = 55.0 degrees Celsius.
The amount of heat absorbed by the water is therefore 32.0 x 55.0 = 1760 calories.
To convert calories to joules, we can use the following conversion factor:
1 calorie = 4.184 joules
Therefore, the amount of heat absorbed by the water in joules is 1760 x 4.184 = 7374 joules.
Therefore, the answer to your question is that 32.0 grams of water absorbs 7374 joules of heat when it is heated from 25.0 degrees Celsius to 80.0 degrees Celsius.

H NMR spectroscopy is used to determine both the---and type of hydrogen atoms in a molecule, whereas 13C NMR is used to determine only the----of carbon atoms in a molecule.
Answers
H NMR spectroscopy is used to determine both the location and type of hydrogen atoms in a molecule, whereas 13C NMR is used to determine only the number of carbon atoms in a molecule.
H NMR (Proton Nuclear Magnetic Resonance) spectroscopy is used to determine both the location and type of hydrogen atoms in a molecule. It provides information about the chemical environment and connectivity of hydrogen atoms within a compound. By analyzing the chemical shifts and splitting patterns in an H NMR spectrum, one can deduce the types of hydrogen atoms present in the molecule (such as methyl, methylene, or aromatic hydrogens) as well as their relative positions.
On the other hand, 13C NMR (Carbon-13 Nuclear Magnetic Resonance) spectroscopy is primarily used to determine the number and types of carbon atoms in a molecule. It provides information about the carbon environments and can help distinguish between different carbon types, such as sp3 hybridized carbons (like in alkanes), sp2 hybridized carbons (like in alkenes), or carbonyl carbons. 13C NMR spectra reveal the chemical shifts of carbon atoms and provide insights into the carbon connectivity within a molecule.In summary, H NMR is used to determine the location and type of hydrogen atoms, while 13C NMR is used to determine only the types of carbon atoms present in a molecule.
