A 58-kg boy swings a baseball bat, which causes a 0.140-kg baseball to move toward 3rd base with a velocity of 38.0 m/s.

1 answer:

3 0

Answer:
101 J
Explanation:
The kinetic energy of an object is given by

where
m is the mass of the object
v is its speed
For the baseball in this problem,
m = 0.140 kg
v = 38.0 m/s
Substituting into the equation, we find the kinetic energy of the ball:

the magnitude of the magnetic field at point p for a certain electromagnetic wave is 2.21. What is the magnitude of the elctic f

vesna_86 [32]

Answer:

$6.63\times 10^8\ N/C$

Explanation:

Given that,

The magnitude of magnetic field, B = 2.21

We need to find the magnitude of the electric field. Let it is E. So,

$\dfrac{E}{B}=c\\\\E=Bc$

Put all the values,

$E=2.21\times 3\times 10^8\\\\=6.63\times 10^8\ N/C$

So, the magnitude of the electric field is equal to $6.63\times 10^8\ N/C$ .

Starting from rest, the distance a freely-falling object will fall in 0.50 second is?

FinnZ [79.3K]

Answer:

1.23 m

Explanation:

The vertical distance covered by a free-falling object starting from rest in a time t is

$y=\frac{1}{2}gt^2$

where

g = 9.8 m/s^2 is the acceleration due to gravity

In this problem, we have

t = 0.50 s

So the distance covered is

$y=\frac{1}{2}(9.8 m/s^2)(0.50 s)^2=1.23 m$
