Answer:
the answer is C
Explanation:
The car, first is at rest and if you don't accelerate it won't move. When to hit the gas it will accelerate from rest
Answer:
I would like to attach options to the question above for clarity.
Jasmine is investigating the effect force has on the motion of an object. She predicts if she puts a strong force on pushing a bowling ball, it will travel a farther distance than when a weak force is applied. Is her prediction correct?
A. No, a weak or a strong force applied to the ball is unable to affect the motion of the ball.
B. No, the force applied to the bowling ball should be a strong force.
C. Yes, the force applied to the bowling ball affects the motion of the ball.
D. Yes, the ball will travel a longer distance when a weak force is applied.
The correct option is C (Yes, the force applied to the bowling ball affects the motion of the ball).
Explanation:
First, a force is any effort either push or pull that causes an object to undergo a change.
A bowling ball can remain at rest or in motion except a force acts on it. This brings us to the question above, the mass which affects force is not mentioned which means it is uniform or negligible. Recall that force = mass X acceleration. So the greater the force that is applied to the bowling ball the further distance it will travel. From the question, she applied a forward force (pushing), so the more force she applies the further the bowling ball will travel.
Answer:
T ’’ = 293º C
Explanation:
Here we must equal the kinetic energy with the thermal energy of the Boltzmann equation
E = K
E = k T
Where k is the Boltzmann constant and T the absolute temperature
K = k T
T ’= 10ºC, the equation to move to Kelvin degrees is
T = (T ’+273) [K]
Let's use the first data
K10 = k T1
We write the second data
2 (K10) = k T2
Let's divide the two equations
2 (K10) / (K10) = k T2 / k T1
2 = T2 / T1
T2 = 2 T1
Now let's write this value in degrees Celsius
(T ’’ + 273) = 2 (T ’+ 273)
T ’’ = 2T ’+ 2 273 -273
T ’’ = 2 T ’+ 273
T ’’ = 2 10 + 273
T ’’ = 293º C
This is the temperature to double the kinetic energy
Answer:
If using radians: 16.2
If using degrees: 12.8
Don't forget your units
Explanation:
I assume that x represents the velocity?
If so, then just substitute the value t and solve
