Answer: Given that:
Mass (m) = 20 g = 0.02 Kg,
temperature (T₁) = -10°C = -10+273 = 263 K
temperature (T₂) = 10°C = 10+273 = 283 K
Specific heat of water (Cp) = 4.187 KJ/Kg k
We know that Heat transfer (Q) = m. Cp.( T₂ - T₁)
= 0.02 × 4.187 × (283-263)
Q = 1.67 KJ
Heat transferred is 1.67 KJ

Answer:
N
Explanation:
We are given that three charged particle are placed at each corner of equilateral triangle.




Side of equilateral triangle =3.3 cm=
We know that each angle of equilateral angle=
Net force=F =
Where k=
If we bisect the angle at
then we have 30 degrees from there to either charge.
Direction of vertical force due to charge
and 
Therefore, force will be added
Vertical force=
Vertical net force=
Vertical force =
Vertical force=
(towards 
Horizontal component are opposite in direction then will b subtracted
Horizontal force=
Horizontal force=
N(towards 
Net electric force acting on particle 3 due to particle =
Net force=
Net force=
N
Answer:

Explanation:
The speed of the actor before the collision is found by means of the Principle of Energy Conservation:



The speed after the inelastic collision is obtained by using the Principle of Momentum Conservation:


Lastly, the maximum height is determined by using the Principle of Energy Conservation again:



Air is a poor conductor of heat. The air trapped between the two panes is a pretty good <em>insulator</em>. It does a lot to prevent heat from flowing through the windows ... keeping heat IN during the Winter, and OUT during the Summer.
Answer:
The details of bands is given in explanation.
Explanation:
The electromagnetic waves are differentiated into different bands based upon their wavelengths and frequencies. The names of different bands are as follows:
1. Radio Waves
2. Micro Waves
3. Infra-red
4. Visible light
5. Ultra Violet
6. X-rays
7. Gamma Rays
<u>The frequency of every region or rays increases from 1 through 7</u>. The <u>energy of rays also increase from 1 through 7</u>. Since, the wave length is inversely related to energy and frequency, thus the <u>wavelength of rays decrease from 1 through 7</u>.
A detailed information of the bands is provided in the picture attached.
