Answer:
Explanation:
Since the compass uses a magnetic field, if anything else magnetic is near it, the compass will start acting up. Making it unreliable so keep magnets away!
Answer:
Explanation:
Given
Length
frequency
Tension in the string
Wave speed in a string is given by
where
wavelength for this wave
and
Hello there!
To find the speed when you have the kinetic energy and the mass, you just start with the kinetic energy formula then solve for speed.
Kinetic energy =
V =
V =
V = 0.02334
Thus, the speed is 0.02 m/s
I hope this helps!
Answer:
<h2>Velocity</h2>
Explanation:
When a body is launched in air and allowed to fall freely under the influence of gravity, the motion experienced by the body is known as a projectile motion. The body is launched at a particular velocity and at an angle theta to the horizontal. The velocity of the body ca be resolved towards the horizontal component and the vertical component.
Along the horizontal Ux = Ucos(theta)
Along the vertical Uy = Ucos(theta)
Ux and Uy are the velocities of the body along the horizontal and vertical components respectively.
This means that the only factor connecting horizontal and vertical components of projectile motion is <u>its velocity</u> since we are able to calculate the velocity of the body along both components irrespective of its initial velocity.
