The acceleration that leads to the increase in the speed of the object is called as Positive acceleration.

Explanation:

The acceleration of a body is defined as the amount of change taking place in the magnitude of the velocity of the body in every second. The acceleration of the body is a vector quantity as it requires the direction along with the magnitude of change in the speed of the body.

If the acceleration of the body is acting in the direction opposite to the direction of motion of the body, then the acceleration tends to decrease the speed of the body and it is called as deceleration.

Whereas if the acceleration of a body is in the direction same as that of the direction of motion of the body, then the acceleration of the body increases the speed of the body and this acceleration is termed as the positive acceleration of the body.

Therefore, the acceleration of an object that tends to speed up the object must be acting in the direction same as the direction of motion of the body and therefore it is termed as the positive acceleration of the body.

Thus, The acceleration that leads to the increase in the speed of the object is called as Positive acceleration.

Explanation:

Acceleration is defined as the change in velocity over time.

When there is an increment or increase in the magnitude of velocity of a moving body then it is known as positive acceleration.

Whereas when there is a decrease in magnitude of velocity of a moving body then it is known as negative acceleration.

Thus, we can conclude that positive acceleration occurs when an object speeds up.

Answer: Because of the reflects back into space equal amount of radiation as it receives.

Explanation: The Earth's temperature doesn't keep rising because as the Earth receives the radiation from the sun, the Earth reflects back an equal amount of that radiation back to space.

This reflective ability of a planet of the sun radiation incident on it is known as the albedo.

Setler79 [48]

Let q1 = -10.0 nC , and q2 = 20.0 nC
E1(P) + E2(P) = 0
|E1| = |E2|
|q1|/r1^2 = q2/r2^2
r2/r1 = sqr(q2/|q1|) = sqr 2
r2 = r1 + d
Solving : r1 = d/(sqr2 -1) = 33.8 cm ; r2 = 47.8 cm
(a) V = (1/4pi €o)(q2/r2 + q1/r1) = 110 V
(b) V=0 |q1|/r1 = q2/r2
r2 = 2 r1 ; r2 + r1 = d
solving
r2 = 28/3 cm ; r1 = 14/3 cm
E = E1 + E2 = (1/4pi€o)(|q1|/r1^2 + q2/r2^2)
E is // at X axis and direct from q2 to q1.
