30 km (20 mi) to 50 km (30 mi)
(1) The parallel force on the Jumper is 441.42 N.
(2) The weight of the person is heavier on Earth when compared to Mars by 610 N.
<h3>
Parallel force on the Jumper</h3>
The parallel force on the Jumper is determined from the parallel components of the weight of the jumper.
F = W x sinθ
F = (85 x 9.8) x sin32
F = 441.42 N
<h3>Weight of the person on Earth</h3>
W = mg
W = 100 x 9.8
W = 980 N
<h3>Weight of the person on Mars</h3>
W = mg
W = 100 x 3.7
W = 370 N
<h3>Difference between the weights</h3>
= 980 N - 370 N
= 610 N
Thus, the weight of the person is heavier on Earth when compared to Mars by 610 N.

#SPJ1
Answer:
Option C
The vectors are perpendicular
Explanation:
Acceleration will be directed towards the center for uniform circular motion. Consequently, velocity of the object increases hence acceleration. The direction of velocity is tangent to its circular motion, therefore, tangential velocity vector is perpendicular to centripetal acceleration vector. Therefore, comparing the direction of the object, the vectors are perpendicular to each other.
Answer:
b and e
Explanation:
r x F is the formula for torque.
The "turning effect" or torque happens when concentric forces rotate an object along said center.
a) False because T = Fr = Ia (a = angular acceleration)
b) True
c) False. L = Iw (w = angular velocity), which does not equal Ia
d) False. It is torque, not the product of torque and something else
e) True.
It's a tough question as to whether light is a wave or a particle..
The statement is FALSE. Not all types of waves need a medium to propagate. Light can travel without a medium.
Extra Information:
Light is a longitudinal wave, sound is transverse.
Longitudinal waves do not need a medium.
Transverse waves need a medium.
This is why, for example, in the vacuum of space, light travels from stars, but sound does not.
