Answer: 6.12 kg

Explanation:

Since Mass of ball = ? (let the unknown value be Z)

Acceleration due to gravity, g= 9.8m/s^2

Height, h = 1.5 metres

Gravitational potential energy GPE = 90J

Gravitational potential energy depends on the weight of the ball, the action of gravity and height.

Thus, GPE = Mass m x Acceleration due to gravity g x Height h

90J = Z x 9.8m/s^2 x 1.5m

90 = Z x 14.7

Z = 90/14.7

Z = 6.12 kg

Thus, the bowling ball weigh 6.12 kilograms

You open the refrigerator in your room and put in a case of room-temperature root beer. After an hour, the root beer is ice cold
agasfer [191]

Answer:

warmer

Explanation:

The law of conservation of energy tells us that energy cannot be created or destroyed, it can be transferred or converted from one from to another. In this question when the beer that is at room temperature is put in the fridge, it loses some heat energy. This heat energy is not destroyed, the fridge through  multiple processes eventually releases this heat to the room through pipes at the back which is why they are normally warm. the heat from the food inside is expelled to the room. It is not lost.

Metabolic syndrome is characterized by all of the following EXCEPT
worty [1.4K]
The term metabolic syndrome defines a group of risk factors which determine your risk for health issues such as heart disease, a stroke and diabetes. Abdominal weight gain (a), elevated blood fat (c) and insulin resistance (d) are all characteristics which will increase your risk of the above health issues. The only characteristic that will decrease your risk of heart disease, diabetes and a stroke is reduced blood pressure (b). If you have any of these negative characteristics, it is important to work at reducing them; thereby, improving your health.
