How much heat is contained in 100 kg of water at 60.0 °C?

1 answer:

8 0

Answer:

so how much heat is there at 0 C? That's zero. But for every degree above that you have 4.184 J. You take it from there. Remember q = mc*delta T.

The kinetic energy of a rotating body is generally written as K=12Iω2, where I is the moment of inertia (also known as rotationa

agasfer [191]

Answer

given,

expression of Kinetic energy of rotating body

$K = \dfrac{1}{2}I\omega^2$

ω = 34.0 rad/s

Assuming mass of the particle equal to 13 Kg

and perpendicular distance from the particle to the axis is r = 1.25 m

now,

moment of inertia of particle = ?

from the given expression

$I= \dfrac{2K}{\omega^2}$ ..............(1)

we know

$K = \dfrac{1}{2}mv^2$

v = r ω

$K = \dfrac{1}{2}mr^2\omega^2$

putting value in equation (1)

$I= \dfrac{2\dfrac{1}{2}mr^2\omega^2}{\omega^2}$

$I =mr^2$

$I =13 \times 1.25^2$

I = 20.3125 kg.m²

( WILL GIVE BRAINLIEST TO WHOEVER ANSWERS FIRST AND SHOWS WORK) A car weighs 15300 N. What is its mass?

mylen [45]

Answer:

Mass, m = 1561.23kg

Explanation:

Given the following data;

Weight = 15300N

We know that acceleration due to gravity is equal to 9.8m/s²

To find mass;

Weight can be defined as the force acting on a body or an object as a result of gravity.

Mathematically, the weight of an object is given by the formula;

$Weight, W = mg$

Where;

m represents the mass of an object measured in kilograms.

g is the acceleration due to gravity measured in meters per seconds square.

Substituting into the equation, we have;

$15300 = m*9.8$

$m = \frac {15300}{9.8}$

<em>Therefore, the mass of the car is 1561.23 kilograms.</em>
