Answer:
The car's angular speed is
.
Explanation:
Angular velocity is usually measured with
, so I'm going to use that to answer your question.
The relationship between tangential velocity and angular velocity (ω) is given by:

Using the values from the question, we get:


Therefore, the car's angular speed is
.
Hope this helped!
The expression, in terms of defined quantities and g is therefore Fu =((mg/2) +2 mp) g
<h3>
What is a Scale?</h3>
This can be defined as a balance or any of various other instruments or devices for weighing.
The expression in terms of defined quantities and g, for the force that the scale under left pillar shows that Fu =((mg/2) +2 mp) g .

Answer:
E = 12640.78 N/C
Explanation:
In order to calculate the electric field you can use the Gaussian theorem.
Thus, you have:

ФE: electric flux trough the Gaussian surface
Q: net charge inside the Gaussian surface
εo: dielectric permittivity of vacuum = 8.85*10^-12 C^2/Nm^2
If you take the Gaussian surface as a spherical surface, with radius r, the electric field is parallel to the surface anywhere. Then, you have:

r can be taken as the distance in which you want to calculate the electric field, that is, 0.795m
Next, you replace the values of the parameters in the last expression, by taking into account that the net charge inside the Gaussian surface is:

Finally, you obtain for E:

hence, the electric field at 0.795m from the center of the spherical shell is 12640.78 N/C
Answer:
2 they detect radio waves
Answer:
259.62521 seconds
Explanation:
= Mass of astronaut = 87 kg
= Mass of wrench = 0.57 kg
= Velocity of astronaut
= Velocity of wrench = 22.4 m/s
Here, the linear momentum is conserved

Time = Distance / Speed

The time taken to reach the ship is 259.62521 seconds
