Answer:

Part a)

a = -9.81 m/s/s

Part b)

v = 0

Part c)

v = 9.81 m/s

Part d)

$H = 4.905 m$

Explanation:

Part a)

During the motion of ball it will have only gravitational force on the ball

so here the acceleration of the ball is only due to gravity

so it is given as

$a = g = 9.81 m/s^2$

Part b)

As we know that ball is moving against the gravity

so here the velocity of ball will keep on decreasing as the ball moves upwards

so at the highest point of the motion of the ball the speed of ball reduce to zero

$v_f = 0$

Part c)

We know that the total time taken by the ball to come back to the initial position is T = 2 s

so in this time displacement of the ball will be zero

$\Delta y = 0 = v_y t + \frac{1}{2} at^2$

$0 = v_y (2) - \frac{1}{2}(9.81)(2^2)$

$v_y = 9.81 m/s$

Part d)

at the maximum height position we know that the final speed will be zero

so we will have

$v_f^2 - v_i^2 = 2 a d$

here we have

$0 - (9.81^2) = 2(-9.81)H$

$H = 4.905 m$

How do light microscopes differ from electron microscopes?

Dennis_Churaev [7]

In light microscope, source is light whereas in electron microscope, source is electron.
Electron microscopes have very low wavelength as compared to light microscope, so it gives larger resolving power.

Hope this helps!

ANSWER = BRAINLIEST<br><br>PLEAASSEE

baherus [9]

1) Mass won't change ( $59$ kg).

2) $W_{TM}=mg_{_{TM}}\medskip\\m=\dfrac{W_{TM}}{g_{_{TM}}}\medskip\\W_{E}=mg_{_E}=W_{TM}\dfrac{g_{_E}}{g_{_{TM}}}=20\times \dfrac{9.08}{1.62}\approx 112.0988$

3) $W_{TM}=mg_{_{TM}}=100\times 1.62=162$

4) $mg_{_{object}}=G\dfrac{M_{object}m}{r^2}\medskip\\g_{_{object}}=G\dfrac{M_{object}}{r^2}$

As $G$ and $r$ are constants, $g_{_{object}}\propto M_{object}$ . In other words, the more massive the object is, the bigger its gravitational acceleration (obviously, the lighter the object is, the lesser its gravitational acceleration)
