Energy. Hope it helps! :)
Answer:
Q = 425 kJ
Explanation:
Given that,
Mass, m = 25 kg
The clown doll head that heats up from 25°C to 35°C
The specific heat is 1700 J/kg°C
We need to find the internal energy of it. The heat required to raise the temperature is given by the formula as follows :
So, 425 kJ of thermal energy is severed.
The triangle stands for change. X means the distance spring stretched or compressed. so together, it's the change in the distance of the spring stretched or compressed.
Answer:
<u>Yes, it will be a Home Run</u>
Explanation:
(Note : It is assumed that the collision between bat and ball is perfectly elastic.)
( Also I don't know anything about baseball, so I checked the dimensions online, which are minimum 325 ft (left and right field foul pole) and minimum 400 ft centre field fence)).
<u>STEP 1</u>
<em>Find</em><em> </em><em>Horizontal</em><em> </em><em>Range</em><em> </em><em>of</em><em> </em><em>Projectile</em><em> </em>
Therefore, the ball will travel 560.3 ft horizontally well beyond 400 ft (largest dimension of the field), and it'll be a Home Run.
