Answer:
Friction
Explanation:
This is because friction tends to oppose the motion of an object. Since the unbalance force or net force causes a motion of the object, the frictional force would tend to oppose the object until it is large enough to balance the net force. When this is done, equilibrium is achieved.
At this instance, there is no net force acting on the object.
So, the forces on the object become balanced and in a state of equilibrium.
If I did my math right I believe 13 is the 9.3 seconds and 14 is the first option because of logic. The question basically says, how does the height change and the answer is the first one because it gets higher then lower, or increases then decreases.
Answer:
1144.8

Answer: <u>Option A: </u>The gas and food are examples of energy.
Explanation:
Work and energy are inter-related. Energy is required to do the work. An equal amount of energy is converted into work. Work and energy have same units. The SI unit is Joule.
The gas and food are sources of energy. They act as fuel. This energy is utilized to perform work. The gas is used to run the car. The food is metabolized inside the body which is a source of energy and utilized to perform every day work.
Hence, The gas and food are examples of energy.
Answer:
Explanation:
a )
The Gaussian surface must have contained both the charges like +3 nC and - 3 nC , total charges being zero . According the Gauss's law , total electric flux over a closed surface is equal to 1 / ε₀ times the total charge contained inside the closed surface .
Since total charge inside is zero , total flux will be 1 / ε₀ x 0 = 0
b )
In this case the Gaussian surface is so small that it contains only the charge
+ 3 nC .
So electric flux over the Gaussian surface
= ( 1 / ε₀ ) x 3 x 10⁻⁹
= (1 / 8.85 x 10⁻¹² ) x 3 x 10⁻⁹
= 3 x 10³ / 8.85
= 339 weber.
