Hello!</h2>
The answer is:
The first option, the force tending to lift Rover is equal to 14.5 N.
<h2>
Why?</h2>
To calculate the force that is tending to lift Rover vertically, we need to calculate the vertical component force.
Since we know that the angle between the force and the ground is 29°, we can calculate the vertical component of the force using the following formula:
We are given that the force is equal to 30.0 N, so, calculating we have:
Also, we can calculate the horizontal component of the force using the following formula:
Hence, we have that the correct option is the first option, the force tending to lift Rover is equal to 14.5 N.
Have a nice day!
Red line -1 because it is just starting out and climbing speed so his energy is at lowest hopefully this helps
Answer:
The electric flux is 
Explanation:
Given:
- Radius of the disc R=0.50 m
- Angle made by disk with the horizontal
- Magnitude of the electric Field
The flux of the Electric Field E due to the are dA in space can be found out by using Gauss Law which is as follows
where
is the total Electric Flux- E is the Electric Field
- dA is the Area through which the electric flux is to be calculated.
Now according to question we have
Hence the electric flux is calculated.
f' = frequency observed by the police car after sound reflected from the vehicle and comes back to police car = 1250 Hz
f = frequency emitted by the police car = 1200 Hz
V = speed of sound = 340 m/s
v = speed of vehicle = ?
frequency observed by the police car is given as
f' = f (V + v)/(V - v)
inserting the values in the above equation
1250 = 1200 (340 + v)/(340 - v)
v = 6.9 m/s
Any force of 29.4 Newtons or greater can do it.
