Answer:
a) , , b) , c) , d) , e)
Explanation:
a) The velocity function is determined by deriving the position function in time:
Velocities after 2 seconds and 4 seconds are, respectively:
b) The maximum height is reached when velocity is equal to zero:
The time when the projectile reaches the maximum height:
c) The maximum height is:
d) The projectile hits the ground when height is equal to zero:
The roots of the second order polynomial are presented below:
The first one is the only reasonable solution in physical terms.
e) The velocity of the projectile when it hits the ground is:
Answer:
it is a sad day for rain to fall. Ill answer your question later
Explanation:
Answer:
3) None of the above
Explanation:
In orbital motion
by lepler law:
Planet sweeps out equal area in equal of time, so angular velocity is conserved.
Angular momentum is also conserved,
so option, 3) None of the above is right.
Answer is
9.773m/s^2
-----------------------------------------------------------------------------
Given,
h=8848m
The value of sea level is 9.08m/s^2. So, Let g′ be the acceleration due to the gravity on Mount Everest.
g′=g(1 − 2h/h)
=9.8(1 - 6400000/17696)
=9.8(1 − 0.00276)
9.8×0.99724
=9.773m/s^2
Thus, the acceleration due to gravity on the top of Mount Everest is =9.773m/s^2

hope this helps :)
the answer is B
the size shape or state of matter changes
because if the shape and size are changing it’s still the same thing.
for example
water to ice
