Answer:
3 m/s
Explanation:
The slope is distance divided by time, also known as 'speed'.
15 meters / 5 seconds = 3 meters per second.
The correct name of the compound is m<span>agnesium nitride.</span>
Answer:
15.2 m/s²
Explanation:
Acceleration: This can be defined as the rate of change of velocity. The S.I unit of acceleration is m/s²
From the question,
F-W = ma......................... Equation 1
Where F = Tension on the line, W = weight of the fish, m = mass of the fish, a = acceleration of the fish.
But,
W = mg........................ Equation 2
Where g = acceleration due to gravity.
Substitute equation 2 into equation 1
F-mg = ma
make a the subject of the equation
a = (F-mg)/m.................... Equation 3
Given: F = 150 N, m = 6 kg,
Constant: g = 9.8 m/s²
Substitute into equation 2
a = [150-(6×9.8)]/6
a = (150-58.8)/6
a = 91.2/6
a = 15.2 m/s²
Hence the minimum acceleration of the fish = 15.2 m/s²
Answer:
THE APPARENT CUBIC EXPANSIVITY OF A LIQUID : is defined as the increase in volume per unit volume per unit rise in temperature when the liquid is heated in an expansible vessel.
Answer:
69 revolutions
Explanation:
given,
initial angular velocity = 0
final angular velocity = 6 rev/s
when safety switch turned off
tub smoothly slows to rest in (t)= 13 s
total revolution of tub = ?
angular acceleration = 
angular acceleration = 
= 0.6 rev/s²
now,
= 30 revolution
now,
when safety switch turn off
angular acceleration =
angular acceleration = 
= -0.462 rev/s²
now,
= 39 revolution
total revolution = 30 + 39 = 69 revolutions.
tub will rotate 69 revolutions
