Answer:
Fog forms in a valley
Explanation: that’s the only reasonable response
The calculation of the centripetal acceleration of an object following a circular path is based on the equation,
a = v² / r
where a is the acceleration, v is the velocity, and r is the radius.
Substituting the known values from the given above,
4.4 m/s² = (15 m/s)² / r
The value of r from the equation is 51.14 m.
Answer: 51.14 m
Answer:
Explanation:
By Ohms Law, Voltage = Current * Resistance
Keeping the voltage the same and doubling the resistance, the current will be halved.
So the new current = 1.5/2 = 0.75A
Answer:
2.019 seconds.
Explanation:
Here we use the equation:
Distance covered = (initial speed x time) + 0.5 x (acceleration x time^2)
The vertical distance to cover is 20 meters.
Since the cannonball is fired horizontally, the initial vertical speed is 0 m/s.
Acceleration due to gravity is 9.81 m/s^2.
Substituting these values into the equation we get:
20 = (0 x time) + 0.5 x (9.81 x time^2)
Solving this equation for time gives us 2.019 seconds as the answer.
