Given Information:
Mass = m = 95 kg
Initial velocity = v₁ = 0 m/s
Final velocity = v₂ = 3 m/s
time = t = 15 seconds
Required Information:
magnitude of average force = ?
Answer:
magnitude of average force = 19 N
Explanation:
From the Newton's second law of motion
F = ma
From the kinematics equations,
v₂ = v₁ + at
at = v₂ - v₁
a = (v₂ - v₁)/t
a = (3 - 0)/15
a = 0.2 m/s²
F = 95*0.2
F = 19 N
Therefore, the magnitude of the average force required to bring the sled to rest is 19 N.
I think the correct answer from the choices listed above is option C. The scatter plot above shows the relationship between the pressure and volume of a gas in which the <span>pressure of a gas increases as its volume decreases. However, they are not linearly related. Hope this answers the question.</span>
Answer:
B
Explanation:
The iris controls the amount of light that enters the eye by opening and closing the pupil. The iris uses muscles to change the size of the pupil. These muscles can control the amount of light entering the eye by making the pupil larger (dilated) or smaller (constricted).
Answer: stratosphere
The stratosphere is the second to last layer of atmosphere to the Earth. It is about 40,000 feet above, and this is the range where planes fly. So, the answer is stratosphere.
Hope this helps!
It is D. An object can acquire a net charge only when charges are transferred to or from it.
