Answer:HERE IS YOUR ANSWER
THE POINTS ARE
IF WE PUT THE OBJECT BETWEEN THE FOCUS
AND THE POLE
THEN THE IMAGE FORMED WILL be MAGNIFIED
If that’s not what you are looking for, try this one:
For concave mirror the virtual image is formed when the object is kept in between the pole and the focus.
Given here the "size of the image" is twice to that of the object.
Hence, it is consider that the magnification is +2.
So, the magnification value is positive and the image formed will be "virtual and erect". Thus, the object should be kept in between the "pole and the focus" in concave mirror."

Answer:
Explanation:
moment of inertia of reel = 1/2 mr² , m is mass and r is radius of the reel
= .5 x .7 x .0524²
= 96.1 x 10⁻⁵
If force required be F
F x .0524 - 1.88 is net torque acting on the reel
F x .0524 - 1.88 = moment of inertia x angular acceleration.
F x .0524 - 1.88 = 96.1 x 10⁻⁵ x 65.7
F x .0524 - 1.88 = .063
F x .0524 = .063 + 1.88
F = 37.08 N

Answer:
Maximum height, h = 10 m
Explanation:
It is given that,
Mass of golf ball, m = 45 g = 0.045 kg
The ball comes down on a tree root and bounces straight up with an initial speed of 14.0 m/s.
We need to find the height the ball will rise after the bounce. It is based on the conservation of energy such that,
h is maximum height raised by the ball
So, the ball will raised to a height of 10 meters.
Answer:
H₂0_{(s)} + heat → H₂O(l)
Explanation:
An ENDOTHERMIC reaction is a chemical reaction in which heat is absorbed by the reactants. As such the product is usually cooler than the products. In the equation above (the answer), heat is on the reactant side of the equation thus indicating that heat is absorbed by the reactants.
On the other hand, in the first equation heat is on the product side of the equation which is consistent with an Exothermic reaction.
