Check all that apply.
Answer: Acceleration and velocity

Just took the test
Answer:
Vector, in physics, a quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity's magnitude. Although a vector has magnitude and direction, it does not have position.
Explanation:
The only thing I found in my notes for this question was this although it isn't in your choices, I just hope this helps you and hope you get it right!
No, the rope would not be strong enough to tow the car since the tension of the rope is less than weight of the car.
The tension in the rope must equal the weight of the supported mass. In this case, the weight of the car is 14,000 N, which is greater than the tension the rope can withstand (12,000 N).
Therefore, this rope would not be strong enough to tow the car. It would require a tension strength of at least 14,000 N.

According to the Newton's second law of motion:
Force = mass × acceleration
Acceleration = change in speed ÷ time
Therefore,
Force =mass × (change in speed/time)
Acceleration = 40 m/s ÷ 1.1 millisecond
Acceleration = 40 m/s ÷ 0.001 seconds
Acceleration = 40,000 m/s²
Hence,
F = m × a
F = 0.155 kg × 40,000 m/s²
F = 4,600 kg·m/s² (Newtons)
How much of your body is made of fat and muscle
How much hair you have
Answer:
How much of your body is made of fat and muscle.
Explanation:
In physical fitness, body composition is used to describe the percentages of fat, bone, water and muscle in human bodies. Because muscular tissue takes up less space in the body than fat tissue, body composition, as well as weight, determines leanness.
