Answer:

Heat can be transfered through a material and non-material medium.

Explanation:

Through a material medium it could be solids, liquid and gas.

In solids the heat transfer process is referred to as conduction. Solids atoms are tightly packed so heat moves on the principle of contact the hotter object warms up the object in contact with. The process continues till all particles of the solid is saturated with a common temperature.

In liquids or gases the heat transfer process is referred to as convection. Here warm particles becomes less dense and become lighter creating room for other cooler particle to fall and fill in the position occupied by the particle before till the whole fluid is saturated with a common temperature.

In a non material medium the heat transfer process is referred to as radiation. Here heat is transferred from source in form of electromagnetic rays.

In which situation are both the speed and velocity of the car changing?

lubasha [3.4K]

Answer is A because the speed and velocity would change. Think of it as GTA, your going 30+ miles per hour and you take a left turn, the speed and velocity would change in an instant..

A 0.560 kg snowball is fired from a cliff 14.2 m high with an initial velocity of 13.3 m/s, directed 26.0° above the horizontal.

enot [183]

Answer:

a) v = 21.34 m/s

b) v = 21.34 m/s

c) v = 21.34 m/s

Explanation:

Mass of the snowball, m = 0.560 kg

Height of the cliff, h = 14.2 m

Initial velocity of the ball, u = 13.3 m/s

θ = 26°

The speed of the slow ball as it reaches the ground, v = ?

The initial Kinetic energy of the snow ball, $KE_{0} = 0.5 mu^{2}$

Potential energy of the snow ball at the given height, PE = mgh

Final Kinetic energy of the ball as it reaches the ground, $KE_{f} = 0.5mv^{2}$

a) Using the principle of energy conservation,

$KE_{0} + PE = KE_{f} \\0.5mu^{2} + mgh = 0.5mv^{2}\\v^{2} =2( 0.5u^{2} + gh)\\v^{2} =u^{2} + 2gh\\v = \sqrt{u^{2} + 2gh} \\v = \sqrt{13.3^{2} + 2*9.8*14.2}\\v = 21.34 m/s$

b) The speed remains v = 21.34 m/s since it is not a function of the angle of launch

c)The principle of energy conservation used cancels out the mass of the object, therefore the speed is not dependent on mass

v = 21. 34 m/s
