The height of the object above the ground is 10 m.
The given parameters;
- gravitational potential energy of the rock, P.E = 196 J
- mass of the rock, m = 2 kg
- acceleration due to gravity, g = 9.8 m/s²
Potential energy of an object is the energy possessed by an object due to its position.
The height of the object is calculated as follows;
P.E = mgh
where;
h is the height of the object above the ground
Thus, the height of the object above the ground is 10 m.

12*6=72 radius of 3, 3*3.14=9.42 so 72+9.42=81.42 :)
Answer:
49
8^2-15
8*8= 64
64-15= 49
Hope this helps :D
.05n + .10d = 6.10
n + d = 67
n = 67-d
.05(67-d) + .10d = 6.10
3.35 -.05d + .10d = 6.10
3.35 + .05d = 6.10
3.35-3.35 +.05d = 6.10-3.35
0.05d = 2.75
0.05d/0.05 = 2.75/0.05
d = 55
n + d = 67
n + 55 = 67
n = 12
There are 12 nickels
Check
0.5(12) + .10(55) = $6.10
.60 + 5.50 =$6.10
$6.10 = $6.10
Answer:
1440
Step-by-step explanation:
Because you just have to mulitply by four to get the answer...
25% x 4 = 100%
360 x 4 = 1440
