A scientist heats an unknown substance in a closed system. The graph shows the change in temperature over time.
Vinil7 [7]

Answer:

C

Explanation:

When a substance is changing state, the heat supplied does not result in a rise in temperature. This is why, the heat supplied during change of state is referred to as 'latent heat'.

Latent heat is a heat that causes a change of state without a corresponding rise in temperature. During this time, the intermolecular bonds in the substance are broken.

Change of state will occur as regions in which there is no change in temperature with time such as point D on the graph.

Which is an example of radioactivity that occurs when a neutron is converted to a proton and an electron is emitted from the nuc
aleksandr82 [10.1K]

Answer:

Beta minus decay

Explanation:

Beta decay is due to a weak nuclear interaction, it takes place in the atomic nucleus and occurs when a neutron is converted to a proton, or a proton into a neutron. When a neutron is converted to a proton an electron and an electronic antineutrino are emitted from the nucleus, this is called beta minus decay.

How do I calculate how many meters are in 7.2 light years?
Vikentia [17]

Answer:

68.2 Quadrillion meters

Explanation:

A lightyear is the distance that light travels in one year.

Speed of light is 3*10^8\ m/s

So light covers 300,000,000 meters in one second.

One year has 31536000 seconds so , light covers

9.461*10^{15}\  meters\ in\ one\ year

so 7.2 light years is

7.2*(9.461*10^{15})\\6.82*10^{16}

so 7.2 light years is

6.82 x 10^(16) meters or

68.2 Quadrillion meters

The Force Of Gravity Acting On A Childs Mass On Earth Is 490 newtons whats the childs mass
Flauer [41]
Force of gravity on an object is the weight of the object and is given by mass times accerelation due to gravity. The accerelation due to gravity is the accerelation of an object in free fall and is given by 9.8m/s^2. Given that the force of gravity acting on a child's mass on earth is 490 newtns, i.e. F = mg which means that 490 newtons = 9.8 times mass. Therefore, mass of the child is 490 / 9.8 = 50 kg.
