Football is a popular ball game and so many people play football these days. Been a contact game, there is no way players will not sustain injuries, but this can be reduced to the lowest point by taking some precautions.
The precautions that could be taken include the following:
Wear the right shoes.
Wear shin guard and soccer socks.
Use the right and properly fitted equipment [helmets, shoulder pads, googles, mouth-guards, etc]. All these equipment should be made for the soccer sport.
To solve this problem we will apply the Newtonian concept of gravitational acceleration produced by a planet. This relationship is given by:
Where,
G = Gravitational Universal Constant
M = Mass of Earth
r = Radius
The values given are based on the constants of the earth, so they can be expressed as
The relationship of gravity would then be given:
The relationship with the new planet, from the gravity of the earth would be given
The relationship with the weight of the earth would be given as:
Therefore the weigh on this planet would be 96N
Answer:Plant Cells have big Vacouls whereas Animal cell have small Vacouls. Plant Cell have cell wall and cell membranes but animal cell has got cell membranes only. Plants cell has Chloroplast and whereas in animal cell it's absent. Plastids absent in animal cell and present in plant cell.
Explanation:
Answer:
Scalar Quantity
Explanation:
A scalar has only magnitude, while a vector quantity has magnitude and direction.
An example of a vector would be 5m/s West.
