Explain specific heat?

Answer»

The specific HEAT is the amount ofheat per unit mass required to raise the TEMPERATURE by ONE degree Celsius. The RELATIONSHIP between heat and temperature CHANGE is usually expressed in the form shown below where c is the specific heat. ... As a result, water plays a very important role in temperature regulation.

Can you measure the average speed and average velocity?

Answer» HOLA MATE ♥♥♥
_______________

Answer

___________


Although SPEED and velocity are often words used interchangeably, in PHYSICS, they are distinct concepts.Speed is calculated by dividing the DISTANCE TRAVELED by time. It does not have direction. Average velocity is thedisplacement (change in position) divided by time.____________________________________

What do you mean by the magnitude of the physical quantity

Answer» PHYSICAL quantity is a physical property of a phenomenon, body, or SUBSTANCE, that can be quantified by measurement. A physical quantity can be EXPRESSED as the combination of amagnitude expressed by a NUMBER – usually a real number – and a unit: where is the magnitude and is the unit.
21.

A body of mass 20kg with a velocity of 30m/s, calculate the kinetic energy of the body.

Answer» KE = 1/2* m * v^2
KE = 0.5 * 20 * (30)^2
KE = 10* 900
KE = 9000 Joules
22.

What do you mean by the magnitude of a physical quantity solution

Answer»

Let's come to an instance.
Suppose, an object is kept on x axis having an acceleration of 2m/s sq. Assuming, body is INITIALLY at rest, it STARTS MOVING.
You would WONDERING that it must move TOWARDS positive x axis. But it's not necessary. I just mentioned that acceleration is 2m/s sq, I didn't comment about its direction.
So, this is the magnitude of the give acceleration which is free of direction given to this physical quantity.

Suppose, the above body has velocity 5m/s at any instant in +ve x axis. Here I m talking about the speed(magnitude of velocity) along with its direction which makes this quantity a pure physical quantity.
Cheers Up!

A ball of 5 kg is thrown upwards with a speed of 10m/s‹a› find the potential energy when it reach the highest point ‹B› calculate the maximum hight attained by it

Answer»

(B) Using the equation of MOTION:
Final Velocity ^2 = Initial Velocity^2 + 2* acceleration * Displacement
V^2 = U^2 + 2*a*s
Given, U = - 10 m/s
Mass = 5kg
Since the velocity will be zero at the highest point, the final velocity (V) =0
0 = 10^2 + 2(-10) * displacement
0 = 100 (-20* displacement)
-100 = - 20 * displacement
- 100 ÷ - 20 = displacement
Therefore, Displacement = 5 meters
So, the maximum height attained by it is 5 meters.
(A) POTENTIAL Energy = MGH
= mass * g * height
= 5 * 10 * 5
= 250 JOULES
Therefore, the Potential Energy at the highest point is 250 Joules.

24.

Answer»

A stone is thrown vertically upwards with an initial velocity of 14 m/s. Neglecting air resistance find (a) the maximum height reached; and (b) the time it has taken to reach the ground.

Answer»

TAKING u=14 V=0 a=g= 10 (9.8) s=x


V SQUARE - u square = 2gs

14×14 -0= 2×10×S

196= 20s

S= 196/20

S= 9.8 METRE

How learn maths and physics easily?

Answer»

physics and maths both are scoring subjects.

in both of them if u know the CONCEPT clearly u can answer any question.

to learn the concept read THEOREMS formulaes  their derivations thoroughly.

in physics lesson read every sentence the chapter because every sentence clear UR mind.

in maths u should read everything carefully and specially in geometry read every point in lesson thoroughly.

i bet if u do this method with good focus and spirit u can easily learn it.

i am 9 studying and i do this method it HELPS me a lot.

these both subjects a are my FAVOURITE . if u check my profile i have answered math and physics questions.
