Answer:

Explanation:
Kinetic energy is the energy an object possesses due to motion. It is calculated with the following formula.

The mass of the object is 4.7 kilograms. The velocity of the object is 7 meters per second.
Substitute the values into the formula.

Solve the exponent.
- (7 m/s)²= 7 m/s * 7 m/s = 49 m²/s²

Multiply the numbers together.


Convert the units. 1 kilogram square meter per square second is equal to 1 Joule.

The object has <u>115.15 Joules</u> of kinetic energy.

Answer:
C
Explanation:
From the question we are told that a vector on the x and y plane face their negative axis
Generally in the x and y plane thr negative y axis is made to face down opposite the positive y axis
Whilst the negative x axis faces the left which is also alternate to the positive x axis
Generally A vector pointing towards the x and y negative axis fro the origin (0) will definitely be in the third quadrant
If an element has a charge of +1, there is 1 more proton than electrons.
A proton has a charge of +1
A neutron has a charge of 0
A electron has a charge of -1.
For there to be a charge of 0, there would be the same amount of charges for both proton and neutron. To get a charge of 1, you will need 1 more proton.
hope this helps
