Answer 1

Answer:

the assertion is false but reson is true

Explanation:

please mark me as brainlest answer

Answer 2

ANSWER

• Speed is a scalar quantity while velocity is a vector quantity.
• Speed is a scalar quantity while velocity is a vector quantity. An object can have constant speed but velocity will change since velocity is a vector quantity.
• Speed is a scalar quantity while velocity is a vector quantity. An object can have constant speed but velocity will change since velocity is a vector quantity. Without having a varying speed non-zero acceleration.
• Uniform circular motion is an example of options B and D

SO THE ASSERTION AND THE REASON ARE CORRECT !!!!

HOPE IT HELPED !!!!!
