Electromagnetism is the interaction between charged particles. It is very long ranged. It can manifest as a force causing like charges to repel and unlike charges to attract. ... The weak nuclear force is very short ranged and is not a force at all.
The formula for gravitational potential energy is Ep= mgh. Lets convert 594 km into m: 594 x 1,000 = 594,000 m. So we do: Ep= (1,800kg)(9.8N/kg)(594,000m) = (17,640N)(594,000) = 10,478,160,000 J.
Answer:
Understanding projections and coordinate systems important knowledge to have, especially if you deal with many different sets of data that come from different sources. Projections Distortion Coordinate Systems Datums
A Cartesian coordinate system. Locations on the Earth's surface are measured and represented in terms of coordinates; a coordinate is a set of two or more numbers that specifies the position of a point, line, or other geometric figure in relation to some reference system.
• Check Layer Properties > Source > Spatial Reference to find out what coordinate system your data is in. If it says “Unknown Coordinate System” you definitely want to use the Define Projection tool. • The Define Projection tool will not make a copy of your data.
Math coordinates identify the location of a point on a graph or map. The ordered pair, (x,y) is the address of the point. The Cartesian coordinate system is the graph used to locate the point.

Answer:
E) V=(m/M)v
Explanation:
Given that
Mass of the small ball = m
Initial velocity of the small ball = v
Mass of the larger ball = m
Initial velocity of the larger ball = 0
After the collision
The velocity of the small ball = 0
The velocity of the larger ball = V
There is no any external force that is why linear momentum will be conserve.
From linear momentum conservation
Pi=Pf
m v + M x 0 = m x 0 + M V
m v +0 = 0 + M V
Therefore the answer will be E.
E) V=(m/M)v
Answer:
1. Since the carpet is softer than the concrete and the force of impact is reduced by the extended time of impact.
Explanation.
The carpet provides energy dissipation over a porous layer of material.
Because of this, the carpet behaves as if it was a spring and a dashpot.
The spring absorbs the kinetic energy, and the dashpot dissipates the energy.
The ticker the carpet, the better the energy dissipation will be.
