An object moving in a circle is accelerating, even if it moves with a constant speed because the velocity changes.
<u>Explanation:</u>
The direction of an object changes constantly during its movement in circle at a constant speed. As the direction changes it results in changing the velocity of that object. This happens since velocity has direction and magnitude.as it is vector quantity.
An object will have acceleration only if a resultant force is acting on that body. When an object is moving in a circle, this resultant force is the centripetal force that is acting towards the center of the circle.
Establishment of new schools and colleges.

Answer:
B. P waves can travel through liquids
Explanation:
P waves or primary waves are elastic waves produced from an earthquake. They are the first waves that arrives a Seismic station when an earthquake disturbs the earth.
P and S waves are both body waves that moves within the earth.
P- waves travel faster than S- waves and can propagate through any medium. S-waves or Secondary waves are shear waves that can only propagate through soilds.
Both waves are longitudinal and moves parallel to their source of propagation. They move by disturbing other particles in their line.
Transverse waves are the love and rayleigh waves. They are both surface waves that travels and cause disturbance on the surface of the earth during an earthquake. They move up and down.
Answer:
D. was rejected at first, but later accepted by the scientific community
Explanation:
when alfred wegener first proposed his theory of continental drift, he was basically a laughing stock in the scientific community. they didn't accept his theory and thought it was crazy and unbelievable. despite this, wegener kept believing in his own theory, but unfortunately it wasn't really until after he died that the scientific community actually accepted his theory of continental drift.
