Energy needed : Q = 1105.5 J
<h3>Further explanation</h3>
Given
mass = 55 g
Temperature from -10°C to 0°C
Required
Energy
Solution
Heat can be calculated using the formula:
Q = mc∆T
Q = heat, J
m = mass, g
c = specific heat, joules / g ° C
∆T = temperature difference, ° C / K
Input the value :
Q = 55 g x 2.01 J/g ° C x (0-(-10))
Q = 1105.5 J
I think it might be B, and A
Answer:
You see things happen much sooner than you hear them.
Explanation:
Light travels about a million times as fast as sound.
When the ball hits the bat , it will take about a million times longer to hear the crack of the bat than to see it.
What you see is almost instantaneous.
There will be a delay until you hear the sound.
The appropriate response is high. The best approach to consider it is those molecules have more vitality than the normal and it is unequivocally those higher enthusiastic ones that have enough vitality to break the intra-molecular forces and leave. By the way this is the reason when we sweat we chill off - the most enthusiastic molecules vanish diverting warmth.
