Answer:
1375J
Explanation:
The gravitational potential/potential energy of the at the top of the tree which is the energy by virtue of its position.
P.E = mgh
mass = m
Acceleration due to gravity = g
height = h
At the top of the tree, the value of h (height) is high resulting in the gravitational potential. When the cat lands on the ground, the value of h is zero, the the gravitational potential would be zero and all the potential energy have been converted to other forms of energy.
Therefore, the total gravitational potential store is equal to the maximum amount of energy that can be transferred which is equal to 1375J.
DIAMONDS are NOT rocks. Diamonds are minerals, rocks are made up of many different fragments of minerals.
Answer:
Explanation:
Force = (mass) · (acceleration)
= (1,000 kg) · (9.8 m/s²)
= 9,800 newtons
Answer:
Angle=70°
Explanation:
Given data
a=2i-5j+k
b=9i-k
To find
Angle Θ
Solution
As we know from dot product rule that

First we need to find a.b
As
i.i=j.j=k.k=1
i.j=i.k=j.k=0
So

Now for |a| and |b|

So the angle is given as

Permeable rock strata or sediment that transmit groundwater freely are called aquifers. These zones should be porous and permeable so as allow entry of water. Rocks of this type are limestone, sandstone, gravel and conglomerate. With these rocks water can move freely and are filtered.
