True: when there is an angle between force and displacement, 
Explanation:
The work done by a force when pushing/pulling an object is given by the equation
where
F is the magnitude of the force
d is the displacement of the object
is the angle between the direction of the force and of the displacement
We have two extreme cases:
- When the force is parallel to the displacement, then 
and 
, so the work done is maximum and simply becomes
- When the force is perpendicular to the displacement, then 
and 
, so the work done is zero.

Answer:
Transverse wave
Explanation:
I hope this helps you! :)
Answer:
0.012 J
Explanation:
We are given:
q = 0.0080C
Potential difference = 1.5V
W=qV
Substituting the values into the equation:
W=0.0080*1.5= 0.012J
Answer: the maximum heigth of the stadium at ist back wall is 151.32 ft
Explanation:
1. use the position (x) equation in parobolic movement to find the time (t)
565 ft = [frac{176 ft}{1 s\\}[/tex] * cos (35°) * t
t= 3.92 s
2. use the position (y) equation in parabolic movement to find de maximun heigth the ball reaches at 565 ft from the home plate.
y= [[frac{176 ft}{1 s\\}[/tex] * sen (35°) * 3.92 s] - 
y= 148.32 ft
3. finally add the 3 ft that exist between the home plate and the ball
148.32 ft + 3 ft = 151.32
