1 answer:

3 0

<span>The first division of political parties came about because of Ratification of the Constitution. There were two opposing parties as a result of this ratification, those who were in favor of a strong centralized government (they were named the Federalists) and those who weren't in favor of that (named Anti-Federalists). This gave rise to the first party systems. </span>

How does increasing the tension of a spring affect a wave on the spring?

Alla [95]

Increasing the tension of a spring affects a wave on the spring because it increases the frequency. When the tension rises, so does the frequency.

A 75kg man goes up a tower 30 m in 120s. How much power did the man exert

Pepsi [2]

Explanation:

If g= 10m/s²

Then 75kg=75×10=750N

Since Work =Force ×Distance

Work=750×30

=22500J

And Power°=Work÷time

=22500÷120

=187.5W

A jewellery shop owner has two identical clear gemstones but cannot remember which one is diamond and which one is rutile. Rutil

pantera1 [17]

We know

$\boxed{\sf n_{21}=\dfrac{C}{V}}$

How he find:-

The owner will measure speed of light through the index(Diamond or rutile).Then using calculations he fill find which is the velocity of diamond or rutile

<h3> For diamond</h3>

$\\ \sf\longmapsto n_D=\dfrac{C}{V_D}$

$\\ \sf\longmapsto 2.4=\dfrac{3\times 10^8ms^{-1}}{V_D}$

$\\ \sf\longmapsto V_D=\dfrac{3\times 10^8ms^{-1}}{2.4}$

$\\ \sf\longmapsto V_D=1.25\times 10^8ms^{-1}$

$\\ \sf\longmapsto V_D=125\times 10^6ms^{-1}$

<h3>For rutile</h3>

$\\ \sf\longmapsto n_R=\dfrac{C}{V_R}$

$\\ \sf\longmapsto V_R=\dfrac{C}{n_R}$

$\\ \sf\longmapsto V_R=\dfrac{3\times 10^8ms^{-1}}{2.9}$

$\\ \sf\longmapsto V_R=1.03\times 10^8$

$\\ \sf\longmapsto V_R=103\times 10^6ms^{-1}$

Dan is gliding on his skateboard at 4.00m/s . He suddenly jumps backward off the skateboard, kicking the skateboard forward at 6

frozen [14]

To solve this problem we will apply the concepts related to the conservation of the Momentum. For this purpose we will define the momentum as the product between mass and velocity, and by conservation the initial momentum will be equal to the final momentum. Mathematically this is,

$m_1u_1+m_2u_2 = m_1v_1+m_2v_2$

Here,

$m_{1,2}$ = Mass of Dan and Skateboard respectively

$u_{1,2}$ = Initial velocity of Dan and Skateboard respectively

$v_{1,2}$ = Final velocity of Dan and Skateboard respectively

Our values are:

Dan's mass

$m_1 = 60kg$

Mass of the skateboard

$m_2 = 7.0kg$

Both have the same initial velocity, then

$u_1= u_2 = 4m/s$

Final velocity of Skateboard is

$v_2 = 6m/s$

Rearranging to find the final velocity of Dan we have then,

$m_1u_1+m_2u_2 = m_1v_1+m_2v_2$

$m_1v_1+m_2v_2 = (m_1+m_2)u_1$

$v_1 = \frac{ (m_1+m_2)u_1 -m_2v_2}{m_1}$

Replacing,

$v_1 = \frac{(60+7)(4)-(7)(6)}{60}$

$v_1 = 3.76m/s$

Therefore Dan will touch the ground at a speed of 3.76m/s

A water tank has a mass of 3.64 kg when empty and 51.8 kg when filled to a certain level. What is the mass of the water in the t

mrs_skeptik [129]

Subtract the total mass of the tank and water by the mass of the empty tank. That will yield the mass of the water.

51.8 - 3.64 = 48.16.

Your answer is 48.16 kg
