Explanation:
Given that,
Weight of the engine used to lift a beam, W = 9800 N
Distance, d = 145 m
Work done by the engine to lift the beam is given by :
W = F d
Let W' is the work must be done to lift it 290 m. It is given by :
Hence, this is the required solution.
Jemima is running with a velocity of 5m/s. She has a mass of 65kg, what is her kinetic energy would be 812.5 Joules.
<h3>What is mechanical energy?</h3>
Mechanical energy is the combination of all the energy in motion represented by total kinetic energy and the total stored energy in the system which is represented by total potential energy.
As given in the problem we have to calculate the Kinetic energy of the Jemima,
Kinetic energy = 1/2 ×mass×velocity²
=0.5×65×5²
=812.5 Joules
Thus, the kinetic energy of the Jemima would be 812.5 Joules.

Zero latitude gets the most direct sun all year around. That's the equator.
The picture you attached has nothing to do with this question.
Correct answer choice is :
B) Red, orange, yellow, green, blue, indigo, and violet
Explanation:
A spectral color is a color that is extracted in a natural human by a single wavelength of light in the apparent rainbow, or by a comparatively narrow band of wavelengths, also recognized as monochromatic light. The combination of colors provided when the light is separated by a prism. Spectrum an indexed order of the elements of an radiation or wave. Electromagnetic rainbow the complete wavelength spectrum of electromagnetic waves.
