Answer:
11250 N
Explanation:
From the question given above, the following data were obtained:
Normal force (R) = 15000 N
Coefficient of static friction (μ) = 0.75
Frictional force (F) =?
Friction and normal force are related by the following equation:
F = μR
Where:
F is the frictional force.
μ is the coefficient of static friction.
R is the normal force.
With the above formula, we can calculate the frictional force acting on the car as follow:
Normal force (R) = 15000 N
Coefficient of static friction (μ) = 0.75
Frictional force (F) =?
F = μR
F = 0.75 × 15000
F = 11250 N
Therefore, the frictional force acting on the car is 11250 N
My answers would be as follows:
<span>You step on the scale and notice that you have lost five pounds. Which of the following has changed?
B) Only your weight changed since mass is conserved. It cannot be destroyed or created.
How could you increase the mass of a wooden block?
D) None of the above. Mass cannot be created so the mass will stay the same it will only be the weight you can increase depending on the acceleration.
If you went to the moon, how would your mass change relative to your mass on Earth?
A) It would be the same on the moon as on Earth. Mass will be the same. It is weight that will change since the gravitational acceleration in the moon is different as that to the earth.

Answer
a) Draw an upward force from the bottom to indicate upthrust
b) Upthrust is an upward force acting on an object floating on a liquid... hence there is an upward force acting on the iceberg which causes it to float.
c) Unfortunately I don't know the answer.
the more pressure put on the string, the more frequency and higher pitch.
Answer:
Potential energy
Explanation:
Potential energy is the energy stored within an object, due to the object's position, arrangement or state. Potential energy is one of the two main forms of energy, along with kinetic energy.
