Answer:
Explanation:
Given data
Change in velocity Δv=14 m/s
Acceleration a=1000 m/s²
Required
Time t
Solution
We know that the acceleration is given by the velocity change over time interval.Therefore
a=Δv/t
Substitute the given values to find time t
So
Answer:
They would have to relocate to a different tree or relocate or a different area that has trees.
Explanation:
Answer:
The potential energy has a maximum when the ball is a time that is half of the time for total travel
Explanation:
Generally potential energy is a the varies directly with the height according to this formula
and the ball attains a maximum height when the time is equal to half of the total time taken to travel
Answer:
150 Nm
Explanation:
Unit conversion:
5 cm = 0.05 m
8 cm = 0.08 m
The torque generated by such force would be the product of the force by the muscles and the moment arm of that force.
T = FR
Where T is the torque (Nm), F = 3000 N is the force and R = 0.05 m is the moment arm
T = 3000*0.05 = 150 Nm
Answer:
The wavelengths of C1 is 10.4m, A6 is 0.193m and B7 is 0.0861m
Explanation:
Using the formula V = f×λ . Then substitute the following values into the formula:
a) v=340m/s
f=32.7 Hz
λ=V ÷ f
= 340 ÷ 32.7
= 10.4m (3s.f)
b) λ=340 ÷ 1760
= 0.193m (3s.f)
c) λ=340÷3951.1
= 0.0861m (3s.f)
(Correct me if I am wrong)
