The block that has a higher temperature describes the thermal energy of these blocks. Thermal energy is a measure of internal energy - therefore, the block with the higher temperature has more internal energy than the block with the lower temperature, meaning it's thermal energy is greater.
A hiker walks 200 m west and then walks 100 m north, the
resulting magnitude is 223 m. The direction can be solve using trigo function
sin angle = opposite/ hypotenuse. Which is equal to 26.6 degree. So the
displacement and direction is 223 m 26.6 degree North of west.
Atomic number of phosphorus is 15
15 electrons.
Explanation:
An atom is made up of subatomic particles. These particles are:
- Protons which are positively charged.
- Electrons are negatively charged
- Neutrons carry no charges.
Atomic number is the number of protons in an atom.
For atoms that has no charge, the number of protons and electrons are the same.
On the periodic table, atoms are arranged based on their atomic number. If phosphorus is the fourth element to the right of sodium, then the atomic number of Phosphorus will be (11+4) = 15.
The atom has no charge and so the number of electrons will be 15 same as the atomic number.

Answer:
The length would be 4.
Explanation:
For this problem, we are going to use the formula, v = lwh. We already have the volume, height, and width, so let's plug it in.
104 = (l)(2)(13)
Now, we have to isolate our variable, which is l. To do this, we multiply 2 and 13 to get 26, and then move it to the other side by dividing both sides by 26.
104/26 = l(26)/26
Then we get 4 = l, which is our answer.
