Something that is really hot and it steams
Answer:
The approximate distance traveled by the ball would be 80 meters in 4 seconds.
Explanation:
Given the canon has a horizontal velocity 140 m/s when it is launched from a tower.
We can see that as was fired horizontally the vertical component of the velocity is zero.
Now, the only force that causes ball to fall to the ground is the gravitational force.
Also, it was given that we need to neglect air resistance.
So, this the condition of free fall. We will use its formula
Where,
is the distance traveled vertically.
is the time of fall.
is .
Plugging these values we get,
So, the approximate distance traveled by the ball would be 80 meters in 4 seconds.
Answer:
the average velocity of the ball is 5 m/s.
Explanation:
Given;
initial position of the ball, x₁ = 12 m East
final position of the ball, x₂ = 8 m West
initial time of motion, t₁ = 10.0 s
final time of motion, t₂ = 6.0 s
The average velocity is calculated as follows;
let the Eastward direction be positive
Let the westward direction be negative
Therefore, the average velocity of the ball is 5 m/s.
Answer: candela
Explanation:
The SI unit for the measurement of intensity is referred to as the candela. The candela is simply used in the measurement of the visual intensity with regards to light sources such as the bulb we have in torches or the light bulbs that we have in our various homes. It is the power that a light source emits in a certain direction.
