They hit the ground at the same time
The stroke that begins a point in volleyball is called a serve
Answer:
Option a
Explanation:
Ocean lithosphere that is 10 million years old is cold enough to be denser than the
asthenosphere so it can sink down into or through the asthenosphere
Answer:
Explanation:
F = qvB
Where F equal to the magnetic force on the particle.
q = charge on the particle
v = velocity of the particle
B =Magnetic field
F = 0.520N
q = 7.4 μC = 7.4×10-⁶C
v = 3×10⁵m/s
B= ?
B = F/qv
B = 0.520/(7.4×10-⁶ ×3×10⁵)
B = 0.234T.
The equation for the gravitational potential energy Ep is:
Ep=m*g*h where m is the mass of the body, g=9.81 m/s² and h is the height of the body.
First we need to find the mass of the body:
m=Ep/(g*h)=24/(9.81*3)=0.82 kg
Now lets see what it's gravitational potential energy would be on the height of 1 m.
Ep=0.82*9.81*1 = 8 J
On the height of 1 m the body has a gravitational potential energy of Ep=8 J.
