Answer:
both magnitude and direction
Explanation:
When an object moves in a circular path, its motion is called uniform circular motion. In this motion, the force acting on it is centripetal force and it is moving under centripetal acceleration. This type of force acts towards the centre of the circle.
In this type of motion, the speed remains constant while the velocity keeps on changing. The object's centripetal acceleration remains constant in magnitude as well as direction.
Hence, the correct option is (3).
It is 72 km/h

Water will boil faster at a higher elevation. Air pressure<span> affects the </span>temperature<span> at which </span>water boils quickly but cooking <span>times will take longer at higher </span>altitudes. This is due to a decrease in atmospheric pressure. An example would be putting an egg to boil. Water boils at lower temperature but the egg <span> involves heating a food to a certain temperature, so, cooking would take longer. </span>
Answer:
B. sugar + oxygen → carbon dioxide + water + energy
Explanation:
Energy is that which sustains living organisms, so as to perform various activities. One of the processes by which living organisms produce energy is by respiration.
Respiration involves the breathing-in of oxygen and breathing-out of carbon dioxide as a waste. The oxygen helps in breaking down molecules of carbohydrates e.g sugar in the system of living organisms into energy, carbon dioxide and water.
This process is well represented by the equation in option B.
B show the potential energy and the kenetic energy
