mrs_skeptik [129]

Answer:

the formula v = f×lambda.

v= 4.25× 5.6

therefore speed is

The method of heat transfer by which the sun energy reaches the earth is
snow_lady [41]

Answer:

Radiation

Explanation:

The heat transfer take place by three modes

1. Conduction

   This type of heat transfer take place in the solid materials like metals .This heat transfer take place due to vibration of electron.

2.Convection

  This type of heat transfer take place in the moving fluid like water ,air etc.

3.Radiation  

 Every materials which having temperature above 0 K are emitting radiation.This type of heat transfer dominate at the high temperature.

We know that temperature of sun is so high so the heat transfer from sun to the earth is take place by radiation mainly.

What are stars made from
kap26 [50]

Stars are made of very hot gas. This gas is mostly hydrogen and helium, which are the two lightest elements. Stars shine by burning hydrogen into helium in their cores, and later in their lives create heavier elements.

A 10n force is applied to a 25kg mass to slide it across a frictional surface. What is the acceleration of the mass?
klasskru [66]

Answer: a = 0.4m/s^2 - 9.8*c where c is the coefficient of kinetic friction of the surface

Explanation: We know that, by the second Newton's law, a = F/m

where a is the acceleration, F is the net force and m is the mass of the object.

Then, if the surface is frictionless, the total force applied in the object is 10N, and the mass of the object is 25kg, so the acceleration is:

a =10N/25kg = 0.4m/s^2.

But if the surface is frictional, there will be a force of friction applied in the mass (this depends on the coefficient of friction and the weight of the mass), this means that the acceleration will be reduced.

If = -(9.8*25)*c

where c is a number that is bigger than 0 and smaller than 1, is called the coefficient of kinetic friction.

So the total force is now:

F = (10 - 9.8*25*c)

Then, the acceleration in a frictional surface is equal to:

a = (10 - 9.8*25*c)/25 = 0.4m/s^2 - 9.8*c
