Answer:
Explanation:
ACCORDING TO NEWTONS SECOND LAW;
F = mass * acceleration
F = m(v-u/t)
m is the mass = 0.15kg
v is the final velocity = 11m/s
u is the initial velocity = 0m/s
t is the time = 0.015
Substitute;
F = 0.15(11-0)/0.015
F = 0.15(11)/0.015
F = 1.65/0.015
F = 110N
Hence the net force is 110N
Answer:
elements in the same column have the same number of neutrons. elements with similar mass are placed in the same column.
When sediment has built up over time layers of rock start to form, starting with sedimentry rocks, then metamorphic rocks
Answer:
A
Explanation:
The roller coaster is stationary so the kinetic energy would be zero, but it is at the top of ramp so the potential energy would be high as its gravitational so it would have to be A
Answer:

Explanation:
As we know that the pressure inside the liquid level is given as

here we have

h = 10.9 km
also we know that

now we have
