The si unit of average speed is m.s. True or False. anyone who is right I will give him brainlist if you are sure​
harkovskaia [24]

True

Explanation:

Average speed is a scalar magnitude as opposed to average velocity which is a vector. The unit of measurement in the International System (S.I.) of the average speed is the meter per second (m/s).

An object is released from rest at time t = 0 and falls through the air, which exerts a resistive force such that the accelerati
rosijanka [135]

Answer:

A) \frac{g}{b}(1-e^{-bt})

Explanation:

Since a = g - bv,

We can substitute a = dv/dt into the equation.

Then, the equation will be like dv/dt = g - bv.

So we got first order differential equation.

As known, v = 0 at t = 0, and v = g/b at t = ∞.

Since \frac{dv}{dt}= g - bv = b( \frac{g}{b} - v) ⇒ \frac{dv}{ \frac{g}{b} - v}= bdt

So take the integral of both side.

- ln (\frac{g}{b} - v) = bt + C

Since for t=0, v = 0 ⇒ C =- ln (\frac{g}{b})

v = \frac{g}{b} + e^{-bt-ln(\frac{g}{b})} = \frac{g}{b}- \frac{g}{b}e^{-bt} = \frac{g}{b}(1-e^{-bt})

What other structures is it near hypothalamus?
Colt1911 [192]
The other structures near the hypothalamus are thalamus and the pituitary gland. 
Hypothalamus is located below the thalamus and is part of the limbic system. It is an integral part of the brain, it is a small cone-shaped structure that projects down ward from the brain, ending in the pituitary stalk, a tubular connection to the pituitary gland.

A student claims that any object in motion must experience a force that keeps it in motion. Do you agree or disagree? Explain yo
frosja888 [35]

Answer:

I disagree

Explanation:

I think the students claim is wrong because according to Newton's First Law an object that is in motion stays in motion unless acted upon by an unbalanced force. Which makes the students claim wrong because a object doesn't require another force to keep it moving.

ThIs is the same type of problem
find out the time value
3 = 1/2*a*T^2
6/10 = t^2
t = 0.77 seconds
and the distance is given 5 m
thus speed ,= distance/time
speed = 5/0.77
= 6.45 m/s
