Venus is the second planet from the sun. It is usually the brightest object in our sky, other than our sun and moon. At sunrise and sunset, it looks like a big, bright star. It is bright because Venus has a cloud cover that reflects the sunlight. These clouds are made up of gases.
Answer: c) 1.31 × 10⁴N
Explanation:
Centripetal force is a force that causes a body to move in a circular path. The body possesses a centripetal acceleration.
According to newtons first law
Force = mass (m) ×acceleration (a)
Acceleration of a body moving in a circular path = v²/r where;
v is the velocity and r is the radius
Force = MV²/r
Given m = 250kg v = 96.5km/hr r = 13.7m
We need to convert 96.5km/hr to m/s
= 96.5km ×1000/1hr × 3600
= 96,500/3,600
v = 26.8m/s
Force = 250 × 26.8²/13.7
Force = 13,106.5N
The centripetal force = 13,106.5N
= 1.31 × 10⁴N
D), because the roller coaster it's falling, therefore, losing height, but gaining velocity
Answer:
A it takes less force to stop the 1 kg ball because it has less inerita
Explanation:
The weight of the ant is the force that acts on the anthill in the <u>downward direction</u> and at angle of 30° rom the vertical.
<u>Given the following data:</u>
- Angle of inclination = 30.0°.
<h3>What is a
free-body diagram?</h3>
In Science, a free-body diagram can be defined as a graphical illustration which is typically used to visualize moments, tension, and applied forces that are acting on an isolated or rigid body (object) while using arrows pointing in the direction of these forces.
In this scenario, the weight of the ant is the force that acts on the anthill in the <u>downward direction</u> and at angle of 30° rom the vertical.
