The car should have less kinetic energy.
They are both going the same speed, but the truck is bigger and heavier. The more mass an object has, the more kinetic energy it has. There is more mass being moved, so it makes more kinetic energy. The car does not have as much mass, so it makes less kinetic energy compared to the truck.

Good luck with the rest of your test or quiz :)

If a scuba diver fills his lungs to full capacity of 5.5 L when 10 m below the surface, to what volume would his lungs expand if
umka21 [38]

Answer:

The volume at the surface is 10.97 L.

Explanation:

Given that,

Volume = 5.5 L

Height = 10 m

Density of sea water= 1025 kg/m³

We need to calculate the pressure at that point

Using formula of pressure

P'=P+\rho gh

Put the value into the formula

P'=1.01\times10^{5}+1025\times9.8\times10

P'=201450\ Pa

We need to calculate the volume at the surface

Using equation of ideal gas

PV= RT

So, for both condition

PV=P'V'

Put the value into the formula

V=\dfrac{201450\times5.5}{1.01\times10^{5}}

V=10.97\ L

Hence, The volume at the surface is 10.97 L.

Light of a wavelength 610nm is incident on a slit of
aleksandrvk [35]

Answer:

0.00915 m

Explanation:

\lambda = Wavelength of light = 610 nm

L = Distance of slit to screen = 1.5 m

a = Slit gap = 0.2 mm

Width of central maximum is given by

w=\dfrac{2\lambda L}{a}\\\Rightarrow w=\dfrac{2\times 610\times 10^{-9}\times 1.5}{0.2\times 10^{-3}}\\\Rightarrow w=0.00915\ m

The width of the central maximum is 0.00915 m

Gina is burning different fuels label the diagram
Anna35 [415]

The answer for the missing labeling as (i) and (ii) will be (i)thermometer and (ii)condenser.

<h3>What is a burner?</h3>

A burner is a device intended to guarantee that the flame is stabilized.

By creating a proper flow field to cause the initial temperature rise, a  The fuel/air combination is heated from within the flame to the ignition temperature.

When the flame or heat is created in fuel-burning or heat-generating equipment.

Wood, coal, kerosene, LPG, petrol, and diesel are a few of the often utilized fuels. In order to cook, heat, power vehicles, and create electricity, we utilize fuels.

The barrel, collar, air holes, gas intake, gas valve, and base are the different pieces of a Bunsen burner. Each component is essential to the process of creating a flame.

Hence, the answers for the missing labeling will be  (i) thermometer and (ii) condenser.
