<h2>Answer:</h2>

<u>Removing nail by the flat end of the hammer is an example of </u><u>using hammer as a lever</u>

<h2>Explanation:</h2>

Lever is a type of simple machine and we know that machine is anything that makes the work of a human easier. By using hammer to remove a nail from wood is an example of lever. The input force is applied on the handle of hammer and a result the output force is experienced at the nail. Fulcrum is the area between the wood and the mouth of hammer by which we will remove the nail.

How does uncertainty relate to measurements and calculations made during an investigation?
DerKrebs [107]
Uncertainty means that your result may be very random, so you can't trust the first or second or so observation, making several samples critical for accuracy. <span />

Answer:

2 m/s²

Explanation:

the equations of motion are

S= ut +½at²

v² = u²+ 2as

v = u + at

s = (u+v)/2 × t

From the parameters given

u = 0m/s this is because it starts from rest

Distance (s)  = 9m

Time (t)  = 3s

Based on this the first equation would be used

s = ut + ½at²

Input values

9 = 0×3 + ½ × a x 3²

9 = 0 + 9a/2

9 = 4.5a

Divide both sides by 4.5

a = 9 / 4.5 m/s²

a = 2 m/s²

Two satellites A and B of the same mass are orbiting Earth in concentric orbits. The distance of satellite B from Earth’s center
riadik2000 [5.3K]

Answer:

ratio of tangential velocity of satellite b and a will be 0.707

Explanation:

We have given distance of satellite B from satellite A is twice

So r_b=2r_a

Tangential speed of the satellite is given by

v=\sqrt{\frac{GM}{r}}, G is gravitational constant. M is mass of satellite and r is distance from the earth

We have to find the ratio of tangential velocities of b and a

From the relation we can see that tangential velocity is inversely proportional to square root of distance from earth

So \frac{v_b}{v_a}=\sqrt{\frac{r_a}{r_b}}

\frac{v_b}{v_a}=\sqrt{\frac{r_a}{2r_a}}

\frac{v_b}{v_a}=\sqrt{\frac{1}{2}}

\frac{v_b}{v_a}=0.707

So ratio of tangential velocity of satellite b and a will be 0.707
