Function of insulators is protection against sound or electric current or ,heat based on the type of insulators.

They use in wires (plastic)

Use in making soundproof rooms

Thermal insulators are use in making water bottles. Keep the water warm

You glide 28 units to the +y-direction with respect to the +x-axis, then move 32 units with respect to the +x-direction. What is

NNADVOKAT [17]

This question can be solved by using Pythagora's Theorem.

The resultant magnitude of the movement is "42.5 units".

The x and y components of the movement are given. We can use Pythagora's Theorem to find the resultant of these movements. Hence, applying the Pythagora's Theorem:

$d = \sqrt{d_x^2+d_y^2}$

where,

d = resultant movement = ?

$d_x$ = movement in x direction = 32 units

$d_y$ = movement in y direction = 28 units

Therefore,

$d = \sqrt{(32\ units)^2+(28\ units)^2}$

d = 42.5 units

1. Calculate the total heat content of 10 kg of ice at -23°C.?

vesna_86 [32]

To solve the problem, we must know the heat capacity of ice and water.

For Cp = 2090 J/kg C

H = mCpT

H = (10 kg) ( 2090 J/ Kg C) ( -23 C)

H = - 480700 J

For water Cp = 4180 j/kg C

H = (100 kg) ( 4180 J/kg C) ( 60 C)

H = 2508000 J
