Answer:

Option (C)

Explanation:

There are eight planets in our solar system.

All the planets revolves around the sun in fixed orbits.

The size of mercury is nearly 38 % of size of earth.

The size of Neptune is 388 % of size of earth.

The size of Uranus is 400 % of size of earth.

The size of Saturn is 945 % of size of earth.

The size of Jupiter is 1120 % of size of earth.

So, the increasing order of sizes of planets is

Mercury < Earth < Saturn < Jupiter.

A force of 5 N accelerates an object. The object’s mass is 50 g. What is the acceleration of the object?

lana [24]

50 g = 0.5 kg. a = 5 / 0.5 = 10 m/s^2.

A 15 kg bucket of water is suspended by a very light ropewrapped around a solid uniform cylinder 0.300 m in diamter withmass 12.

matrenka [14]

Answer:

Part a)

$T = 42 N$

Part b)

$v_f = 11.8 m/s$

Part c)

$t = 1.7 s$

Part d)

$F = 159.7 N$

Explanation:

Part a)

While bucket is falling downwards we have force equation of the bucket given as

$mg - T = ma$

for uniform cylinder we will have

$TR = I\alpha$

so we have

$T = \frac{1}{2}MR^2(\frac{a}{R^2})$

$T = \frac{1}{2}Ma$

now we have

$mg = (\frac{M}{2} + m)a$

$a = \frac{mg}{(\frac{M}{2} + m)}$

$a = \frac{15 \times 9.81}{(6 + 15)}$

$a = 7 m/s^2$

now we have

$T = \frac{12 \times 7}{2}$

$T = 42 N$

Part b)

speed of the bucket can be found using kinematics

so we have

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

$v_f^2 - 0 = 2(7)(10)$

$v_f = 11.8 m/s$

Part c)

now in order to find the time of fall we can use another equation

$v_f - v_i = at$

$11.8 - 0 = 7 t$

$t = 1.7 s$

Part d)

as we know that cylinder is at rest and not moving downwards

so here we can use force balance

$F = T + Mg$

$F = 42 + (12 \times 9.81)$

$F = 159.7 N$
