Answer:
Heat Lost = (120 - 12.6) deg * 170 g * S = `18260 gm-deg * S
Heat Gained = (12.6 - 10) deg * 200 gm* 1 cal/ gm-deg - 520 cal
S = 520 / 18260 cal / gm-deg = .0285 cal / gm-deg
Since Heat Lost = Heat Gained
Explanation:
If water is being put in fridge it will get freezed.
The acceleration of the object after 3 seconds of fall is -9.8 m/s².
The given parameters;
- initial velocity of the object, u = 0
- time of motion of the object, t = 3 seconds
Acceleration is the change in velocity per change in time of motion.
The acceleration of the object after 3 seconds of fall is calculated as follows;
- Since the object is in free fall, the object experiences only acceleration due to gravity.
- the magnitude of this acceleration due to gravity is 9.8 m/s²
- the direction of this acceleration is downwards
Thus, the acceleration of the object after 3 seconds of fall is -9.8 m/s².

Tere would be too many so there would be more fighting. Thye could overpopulate the world and destroy our stuff for example if it is a pig they can easily destory crops. We would all have to go hunting. There would also be less food so that is why they would start going out and destroying stuff.
