Why would it be hard to find the ideal light intensity if the temperure were very hot or cold?
grandymaker [24]
The correct answer for this question is this one:

Light intensity is not dependent on temperature, with that said, plants (assuming that is what were talking about) would dehydrate faster at a higher temperature (unless they had mechanisms to cope e.g. C4 and CAM plants) with the same light intensity.

Two factors affect the amount of thermal energy in an object, The amount of space between its particles and The amount of motion
Arturiano [62]

Answer:

<em>The thermal energy of an object depends on its temperature and mass. The higher the temperature of a substance, the more thermal energy it has. For the same temperature, a substance with a higher mass will also have more thermal energy.</em>

You drop two rocks. one rock has a mass of 8kg and the other a mass of 7kg. The 8kg rock falls no faster than the 7kg rock for w
murzikaleks [220]

Answer:

The gravitational force is significantly constant.

Explanation:

The gravitational force is expressed as:

F= G*M*m/d^2

G= Gravitational constant

M= in this case it is the mass of the planet

m= mass of the rock

d= distance of the rocks from the ground (suppose both at the same height for better comparison)

At the same time, we know that the force that each rock experiences is equal to the product of the mass due to acceleration:

F=m*a

We can match both expressions for F:

G*M*m/d^2 = m*a

we simplify m, and we obtain that the acceleration is independent of the mass of the attracted bodies:

a= G*M/d^2

If a ball is 10m high with what velocity will it fall?
Semmy [17]

14m/s

Explanation:

Given parameters:

Height of the ball = 10m

Unknown:

Velocity of fall or final velocity = ?

Solution:

We are going to use the appropriate equation of motion to solve this problem.

The object is falling with respect to gravity.

  V² = U² + 2gH

where V is the final velocity

            U is the initial velocity

             g is the acceleration due to gravity 9.8m/s²

             H is the height of fall

The initial velocity here is zero and

      V² = 2 x 9.8 x 10 = 196

       V = 14m/s
