Answer:
2000 kg
Explanation:
Given that Which will have a larger momentum when moving at the same speed: a 2,000-kg truck or a 1,000-kg sedan
According to the definition of momentum, momentum is the product of mass and velocity.
That is,
Momentum = mass × velocity
Since velocity or speed is the same, then, the one of higher mass will have a greater momentum.
Therefore, the 2000 kg truck will have the greater momentum.
Answer:
option (b) 4900 N
Explanation:
m = 2000 kg, R = 6380 km = 6380 x 10^3 m, Me = 5.98 x 10^24 kg, h = R
F = G Me x m / (R + h)^2
F = G Me x m / 2R^2
F = 6.67 x 10^-11 x 5.98 x 10^24 x 2000 / (2 x 6380 x 10^3)^2
F = 4900 N
Answer:
Part a)
![T_L = 155.4 N](https://tex.z-dn.net/?f=T_L%20%3D%20155.4%20N)
Part b)
![T_R = 379 N](https://tex.z-dn.net/?f=T_R%20%3D%20379%20N)
Explanation:
As we know that mountain climber is at rest so net force on it must be zero
So we will have force balance in X direction
![T_L cos65 = T_R cos80](https://tex.z-dn.net/?f=T_L%20cos65%20%3D%20T_R%20cos80)
![T_L = 0.41 T_R](https://tex.z-dn.net/?f=T_L%20%3D%200.41%20T_R)
now we will have force balance in Y direction
![mg = T_L sin65 + T_Rsin80](https://tex.z-dn.net/?f=mg%20%3D%20T_L%20sin65%20%2B%20T_Rsin80)
![514 = 0.906T_L + 0.985T_R](https://tex.z-dn.net/?f=514%20%3D%200.906T_L%20%2B%200.985T_R)
Part a)
so from above equations we have
![514 = 0.906T_L + 0.985(\frac{T_L}{0.41})](https://tex.z-dn.net/?f=514%20%3D%200.906T_L%20%2B%200.985%28%5Cfrac%7BT_L%7D%7B0.41%7D%29)
![514 = 3.3 T_L](https://tex.z-dn.net/?f=514%20%3D%203.3%20T_L)
![T_L = 155.4 N](https://tex.z-dn.net/?f=T_L%20%3D%20155.4%20N)
Part b)
Now for tension in right string we will have
![T_R = \frac{T_L}{0.41}](https://tex.z-dn.net/?f=T_R%20%3D%20%5Cfrac%7BT_L%7D%7B0.41%7D)
![T_R = 379 N](https://tex.z-dn.net/?f=T_R%20%3D%20379%20N)
Wavelength = speed / frequency
(345 m/s) / (20,000 Hz) = 0.017 m
