Aparticle follows a planar path defined by x = kξ, y = 2k[1 − exp(ξ )], such that its speed is v = βξ, where k and β are constants. determine the velocity and acceleration at ξ = 0.5

The velocity of the particle is given by the derivative of the position vector . We have

with derivative

At , we get a velocity vector of

Not important as far as I can tell, but the particle's speed at is , which satisfies

(Perhaps you may be required to solve for in terms of , then report the velocity/acceleration vectors with respect to , but I'll not do so because the original question makes no mention of needing to do that.)

Acceleration is given by the derivative of the velocity vector:

and at , the acceleration vector is

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the

happy to

pls mark as brainliest.
