It was Niels Bohr who proposed it
Answer:
1.498×10⁵ Nm
Explanation:
From the question above,
Torque (T) = Force (F) × radius (r)
T = F×r............................. Equation 1
Where T = Torque, F = force, r = radius .
Given: F = 2.27×10⁵ N, r = 0.660 m
Substitute these values into equation 1
T = 2.27×10⁵×0.660
T = 1.498×10⁵ Nm
Hence the torque of the wheel is 1.498×10⁵ Nm
Answer: D. 12 m/s
Explanation:
Use the formula of then just solve by inserting the numbers.
You use the first mountain height(5) and the second mountain height(12) and insert to the equation.
Sole and you'll be left with 12.
Add the labeling "m/s"
and youre done!
tehe ur welcome vanessaaa
Answer: 0.145 seconds
Explanation:
Given that Roger Clemens could routinely throw a fastball at a horizontal speed of 119.7 m/s. How long did the ball take to reach home plate 17.3 m away
Since the speed is horizontal
Using the formula for speed which is
Speed = distance/time
Where
Speed = 119.7 m/s
Distance covered = 17.3 m
Time is what we are looking for
Substitute all the parameters into the formula
119.7 = 17.3/ time
Make time the subject of formula
Time = 17.3 / 119.7
Time = 0.145 seconds.
Therefore, it will take 0.145 seconds to reach the home plates
I think the answer is Phylogeny, I also hope this helps you!
