A car travels with an average speed of 22 m/s.what is this speed in km/s
2 answers:
Answer:
22 m/s = 79.2 km/h
Explanation:
Given that,
The average speed of the car is 22 m/s. Here, we need to convert the speed to km/h. Firstly, we will see the following conversions as :
1 kilometres = 1000 meters
1 hour = 3600 seconds
To convert m/s to km/h we must use these coversions.
After solving the above expression, we get
22 m/s = 79.2 km/h
So, the car travel with a speed of 79.2 km/h. Hence, this is the required solution.

Answer:
Explanation:
The magnitude of the force of a moving cahrge, in our case a proton, trought a magentic field is given by:
(1)
where:
q is the proton charge ()
v is the proton velocity ()
B is the magnetic field (B = 1.17 T)
Now, we just need to solve the equaton (1) for \theta.
But the force F = ma, then:
m is the mass of proton ()
a is the acceleration ()
