Answer:
jus did this, the answer is A, -0.8 m/s^2 :)
Explanation:
Answer:
507599.78 J
Explanation:
Charge input = current x time
=15 x 53 x 60
= 47000 coulomb
increase in voltage
= 12.6 - 9 = 3.6
capacity of the battery C = Charge input / increase in voltage
= 47000 / 3.6 = 13055.55
energy of the capacitor = 1/2 CV²
Initial energy of car battery = .5 x 13055.55 x 9 x 9
= 528749.77 J
Final energy of car battery
= .5 x 13055.55 x 12.6 x 12.6
= 1036349.55
Increase in energy = 507599.78 J
Answer:
Angle of twist;Φ = (to•L²)/Gπc⁴
Explanation:
I have attached the explanation.
However, I used D for radius of shaft against c used in the question. So, if we replace the D with c, we'll have;
Φ = (to•L²)/Gπc⁴
Answer:
A ball is thrown in an arbitrary direction and a rocket moves through the sky after its engines have failed.
Explanation:
The concept applied is that of projectile motion which is the free fall for both then horizontal and vertical component of a constant velocity. it is also the motion of an object thrown under the influence of acceleration due to gravity.
The correct option are as follows ; A ball is thrown in an arbitrary direction and a rocket moves through the sky after its engines have failed.
For the first case ; A ball is thrown in an arbitrary direction ; after the ball must have been thrown, the projectile further moves in a curved path.
for the second case ; A rocket moves through the sky after its engines have failed ; the rocket also moves in a curved path under the influence of the acceleration due to gravity.
To isolate v₁ from the given equation, subtract aΔt from both members of the equation and simplify:
Therefore, the formula for v₁ is:
