A force of 5.5N is applied to an object. The moment arm for the force is 0.84 m, the torque produced by the force is <u>4.62N-m</u>.
A force applied perpendicularly to a lever multiplied by its distance from the lever's fulcrum (the length of the lever arm) is its torque. We can find the torque from a force by taking the perpendicular component of that force and multiplying by the magnitude of the R vector where this R vector is the vector that points from the axis to the point where the force is applied.
To calculate torque produced by the force, we have-
Torque= forcexmoment arm
T = fxd
T =5.5Nx0.84m
T=4.62N-m.

The Gravitational PE (U) depends on three things: the object’s mass (m), its height (h), and gravitational acceleration (g), which is 9.81 m/s^2 on Earth’s surface.
so U = mgh = 9.81mh on earth
mass of the car = 50.0 grams = 0.05kg
height, h:
Hill 1 = 90.0 cm = 0.9m,
Hill 2 = 65.0 cm = 0.65m,
Hill 3 = 20.0 cm = 0.2m
substitute into eqn U = mgh
U @ top of Hill 1 = 0.05*9.81*0.9 = 0.4415J
U @ top of Hill 2 = 0.05*9.81*0.65 = 0.3188J
U @ top of Hill 3 = 0.05*9.81*0.2 = 0.0981J
difference in Gravitational Potential Energy from the top of Hill 1 to the top of Hill 3 = 0.4415 - 0.0981
= 0.3434J where J is the unit for energy, Joules
Answer:
B
Explanation: a chemical reaction is only the rearrangement of electrons where a nuclear reaction actually changes the elements and thus the nuclei
The first shell has 2 in and the second shell has 8 in therefore ypuvwont need to add anymore :-) so the answer is 0
The left end of the string is given as y = - 0.100 sin (3.14t )
<h3>How to find the sinusoidal wave</h3>
We would have to create an equation of this form
The wave function equation
y = A sin ( π*x - ω* t )
When we put in the values that we have in the equation
y = 0.100 sin ( 3.14 x - 3.14 t )
Due to the fact that it is the left end of the string, the value that we would have for x is going to be 0, hence we would have
y = 0.100 sin (3.14 * (0) - 3.14t )
Then y would be 0.100 sin (- 3.14t )
This would give us the final equation
y = - 0.100 sin (3.14t )
Hence we would have the left end of the string as y = - 0.100 sin (3.14t )
