Answer:

They have the same rate of motion.

Explanation:

Electromagnetic radiation is a type of energy that is commonly known as light. Generally, light travels in waves, and all electromagnetic radiation travels at the same speed, which is about 3.0 × 108 ms− 1 through a vacuum.

The Schwarzschild radius of a black hole depends on the mass and density of the black hole because volume is the space that an object occupies.

Volume is defined as the amount of space occupied by an object. It can be measured in cubic units. If the black hole has more volume then it has more radius and vice versa.

So we can conclude that the Schwarzschild radius of a black hole depends on the mass and density of the black hole because volume is the space that an object occupies.

Answer:

At the same speed as before

Explanation:

Speed is dependent on the tension in the string, and since the tension isn't changing, the speed of the waves will also not change.

The total time for the whole journey  =  7 hours

Distance = Speed  x  time

Distance traveled for the first 3 hours

time = 3 hours

speed = 60 km/h

Distance = 60  x  3

Distance = 180 km

180 km was traveled for the first three hours

Total distance traveled = 460 km

Distance traveled at an average speed of 70 km/h  = 460  -  180

Distance traveled at an average speed of 70 km/h  =  280 km

Speed  =  Distance / time

70   =  280 / time

time = 280 / 70

time = 4 hours

Mr. Ben traveled 3 hours at an average speed of 60 km/h, he traveled 4 hours at an average speed of 70 km/h.

The total time for the whole journey = 3 hours + 4 hours

The total time for the whole journey  =  7 hours

the conservation of both matters because without each other the balance of nature will be destroyed it helps in such a way that the food chain will be maintained.

it is as such considered because without matter there would be no energy and the reverse is such.

it is still considered because without one another famous atomic theories wouldn't have been made such as gas, liquid and solid.

in conclusion all these work together to balance the galaxy as a whole

Both the conservation of energy and the conservation of matter is important because, without each other, the natural equilibrium will be disrupted.

According to the Law of conservation of energy. Energy can not be created nor be destroyed it can transfer from one to another form.

The total energy is the sum of all the energies present in the system. The potential energy in a system is due to its position in the system.

The conservation of both is important because without each other, the natural equilibrium will be disrupted, and it aids in the maintenance of the food chain.

It is seen as such because there would be no energy without matter and vice versa.

Hence both the conservation of energy and the conservation of matter is important

Answer:

[tex]104\; {\rm g}[/tex], assuming that the meter stick is uniform with the center of mass precisely at the [tex]50\; {\rm cm}[/tex] mark.

Explanation:

Refer to the diagram attached. The meter stick could be considered as a lever. The string at the [tex]30\; {\rm cm}[/tex] mark would then act as the fulcrum of this lever.

The [tex]m_{A} = 20\; {\rm g}[/tex] mass at the [tex]80\; {\rm cm}[/tex] mark is at a distance of [tex]r_{A} = 50\; {\rm cm}[/tex] to the right of the fulcrum at [tex]30\; {\rm cm}[/tex].

The weight of the [tex]80\; {\rm g}[/tex] meter stick acts like a weight of [tex]m_{B} = 80\; {\rm g}[/tex] attached to the center of mass of this meter stick. Under the assumptions, this center of mass of this meter stick would be at the [tex]50\; {\rm cm}[/tex] mark, which is [tex]r_{B} = 20\; {\rm cm}[/tex] to the right of the fulcrum at [tex]30\; {\rm cm}[/tex].

Let [tex]m_{C}[/tex] be the mass attached to the meter stick at the [tex]5\; {\rm cm}[/tex] mark. This mass would be at a distance of [tex]r_{C} = 25\; {\rm cm}[/tex] to the left of the fulcrum at [tex]30\; {\rm cm}[/tex].

At equilibrium:

[tex]\begin{aligned} & m_{C}\, r_{C} && (\text{mass on the left of fulcrum})\\ &= m_{A}\, r_{A} + m_{B} \, r_{B} && (\text{mass on the right of fulcrum})\end{aligned}[/tex].

Solve for [tex]m_{C}[/tex], the unknown mass attached to the meter stick at the [tex]5\; {\rm cm}[/tex] mark:

[tex]\begin{aligned}m_{C} &= \frac{m_{A}\, r_{A} + m_{B}\, r_{B}}{r_{C}} \\ &= \frac{20\; {\rm g} \times 50\; {\rm cm} + 80\; {\rm g} \times 20\; {\rm cm}}{25\; {\rm cm}} \\ &= 104\; {\rm g}\end{aligned}[/tex].

It can be assumed that the spring constant will be same.Because the weight applied and the extension is same

The force required to extend or compress a spring by some distance scales linearly with respect to that distance is known as the spring force. Its formula is

F = kx

Two springs are attached to two hooks. When equal weights are suspended from each spring, both stretch the same amount.

Extensions will be greater in spring B than in spring A.Remember that the force constant represents the spring's stiffness,

Hence It can be assumed that the spring constant will be same.Because the weight applied and the extension is same.

Answer:

Moment of inertia at distance L / 2    from center

I1 = M (L / 2)^2 = M L^2 / 4

I2 = M (L / 6)^2 = M L^2 / 36      at a distance of L / 6

I (1/2 rod) = I1 + I2 = M L^2 (1/4 + 1/36) = M L^2 (9 + 1)/ 36 = 5/ 18 M L^2

I for entire rod = 2 I (1/2 rod) = 5 / 9 M L^2
