When the suns energy moves through space it reaches earths atmosphere and finally the surface it warms the atmosphere and becomes heat energy then its transfared throughout the planets system by radiation conduction and convection
Answer:
- 0.5 m/s
Explanation:
(1) Acceleration = change in velocity / time
(2) Change in velocity = (Final velocity - Initial velocity)
We know:
acceleration = 1.5 m/s/s
time = 5 seconds
final velocity = 7 m/s
x = initial velocity)
1.5 = ( 7 - x ) / 5
1.5 x 5 = ( 7 - x )
7.5 = 7 - x
x = -0.5 m/s
You can check the answer by plugging in the values to equation (1).
The correct answer to this question is <span>48.8N</span><span> on a bearing of </span><span>134.2 degrees.
In order to solve this, first we need to find the resultant force of the men pulling in the north and south directions:
F = 40 - 6 = 34N [due south - 180]
Then, find the resultant force.
R^2 =34^2 + 35^2
R^2 = 2381
R = sqrt(2381)
R = 44.8N
The angle from the vertical is given by:
tan(x) = 35/34
tan(x) = 1.0294
angle = 45.8 degrees
Taking N as zero degrees, then it bears 134.2 degrees.
