Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. The earliest roots of science can be traced to Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE.

In golf, a club is swung to hit a small ball resting on the ground. Golfer A holds his club a short distance behind the golf bal
klemol [59]

Answer:

Golfer B hits his golf ball at a higher rate of speed and with more force. This means that golfer B's ball will travel for a longer period of time and a longer distance due to newtons first law, where it says an object in motion stays in motion, with the same speed and in the same direction.

What is the unit for measuring energy
sdas [7]
This would be called a Joule. The formula for energy is <span>P.E. = mgh (otherwise known as the gravitational force formula, which is energy.) M is the mass in kilograms, and G is the acceleration due to gravity, which is actually (9.</span>8 m / s2<span> at the surface of the earth.) I hope this helps! ~Mia</span>

A neutron has a kinetic energy of 10 MeV. What size aperture would be necessary to observe diffraction effects?
Sedaia [141]

Answer: 9.33fm

Explanation:

Similarly as with a cut diffraction happens when part of the proliferating wave is cut off. This will occur for any object of request with a similar size as the wavelength of the diffracting wave.

Note, the object is moving at 14% of the speed of light. Be that as it may, the gamma factor is just 1% so taking care of the issue either relativistic or non relativistic conditions offers comparative responses.

Note: The size of the object has to be of the order of the wavelength of 10MeV. Therefore, size apperture that would be necessary to observe diffraction effect would be 9.33fm.

The calculations are in the attachment below:

An 8.2 kg object accelerates at 8.0 m/s^2. What is the acceleration?
Elina [12.6K]

Answer:

under

Explanation:

We know that F = ma,

or, a = F/m

or, a = 120/30 (because, Force = 120 N and mass = 30 kg)

or a = 4m/s^2

Hence, the acceleration of the object is 4 meter per second squared.
