Answer:
5.61 seconds
Explanation:
The baseball moves as a projectile. Its angle is 45° and its velocity is 95 miles per hour.
Let us convert this to metres per second:
1 mile per hour = 0.45 m/s
95 miles per hour = 95 * 0.45 = 42.75 m/s
We need to find the time of flight of the baseball. Time of flight is given as:
where u = initial velocity
α = angle
g = acceleration due to gravity (9.8 m/s)
Therefore:
The baseball was in the air for 5.61 seconds.
Answer:
The magnitude of the force on the moving charge is
Explanation:
Given that,
Current = 5.0 A
Charge
Speed v = 100 m/s
Distance = 0.1
We need to calculate the magnitude of the force on the moving charge
Using formula of force
Put the value into the formula
Hence, The magnitude of the force on the moving charge is
