Answer: It spreads forming waves

Explanation:

Radiant energy is the one possessed by electromagnetic waves such as visible light,  (IR) rays, ultraviolet (UV) rays, radio waves, etc. The main characteristic of this energy is that it can be propagated in a vacuum, without the need for any material support.

Other properties are:

- It is in motion continuosly

- Travel through space at the speed of 300,000 kilometers per second

- It spreads forming waves.

29. If a walnut is burned in a
harkovskaia [24]

Energy were released from the walnut, q = 1,673.6 J

<h3>Equation :</h3>

To find the energy using formula,

q = mcΔt

where,

q is charge

m is mass

c is specific heat of water

Δt is change in temperature

So, given

t₁ = 50°C

t₂ = 60°C

m = 40g

c = 4.184 J/g

Now putting the values known,

We get,

q = mc(t₂ - t₁)

q = 40g x 4.184 J/g x  (60 - 50)

q = 167.36 J x 10

q = 1,673.6 J

<h3>What is heat energy?</h3>

Heat is the thermal energy that is transferred when two systems with different surface temperatures come into contact. Heat is denoted by the letters q or Q and is measured in Joules.

The table below gives the numbers of protons, electrons, and neutrons in four atoms.
PolarNik [594]

Answer:

Atom 3

Explanation:

Protons have a +1 charge, electrons have a -1 charge, and neutrons have no charge and are therefore neutral. The charges will cancel each other when equal. To determine which atom has the a -1 charge, find the atom that has one more electron than it has protons.

3. ml of 1.00 M LiOH to 500.00 ml of 0.075 M of LiOH (Dilution Problem)​
castortr0y [4]

The volume (in mL) of the 1.00 M LiOH needed to prepare 500.00 mL of 0.075 M of LiOH is 37.5 mL

<h3>How do I determine the volume (in mL) of LiOH needed?</h3>

Dilution formula is given as follow:

M₁V₁ = M₂V₂

Where

  • M₁ is the molarity of stock solution
  • V₁ is the volume of stock solution
  • M₂ is the molarity of diluted solution
  • V₂ is the volume of diluted solution

Applying the above formula, we obtain the volume (in mL) of LiOH needed to prepare 500.00 mL of 0.075 M of LiOH. This is illustrated below:

  • Molarity of stock solution of LiOH (M₁) = 1.00 M
  • Volume of diluted solution of LiOH (V₂) = 500.00 mL
  • Molarity of diluted solution of LiOH (M₂) = 0.075 M
  • Volume of stock solution of LiOH needed (V₁) =?

M₁V₁ = M₂V₂

1 × V₁ = 0.075 × 500

V₁ = 37.5 mL

Thus, the volume (in mL) of LiOH needed is 37.5 mL
