EQUATOR IS THE LINE THAT DIVIDES EARTH INTO TWO HEMISPHERES .
If it is not exposed to sunlight often... then it might not be able to produce sufficient amounts
Answer:
d = 7200 m
Explanation:
Given that,
Average speed of a runner, v = 2 m/s
Time taken by the runner, t = 60 min = 3600 s
We need to find the distance covered by the runner.
Speed = distance divided by time taken.
v = d/t
Putting all the values,
So, the distance covered by the runner is 7200 m.
Answer:
Explanation:
Time of flight is the time taken by the bulet in air. Time of flight is expressed as T = Usinθ/g where;
U is the initial velocity = 180m/s
θ is the angle of launch = 90° (Since the bullet is shot upwards)
g is the acceleration due to gravity = 9.81m/s²
T = 180sin90/9.81
T = 180/9.81
T = 18.35s
<em>Hence the bullet will spend 18.35s in air</em>
<em></em>
The height covered by the bullet is the maximum height. Maximum height is expressed as;
H = u²sin²θ/2g
H = 180²sin²90/2(9.81)
H = 180/19.62
H = 9.17m
<em>Hence the bullet will go 9.17m high</em>
Answer:
20 N up
Explanation:
Since the object on the floor is sitting still. Based on Newton's law of force. Objects must have equal reaction and force against each other for still objects. So the answer is 20 N up. Since the force are equal on both sides making the object not moving.
