Force = mass × acceleration
static force = coefficient of friction × normal force
1.70 = 0.0600 × normal force...
normal force = 1.70 ÷ 0.0600.. to obtain....
Explanation:
The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside. ... is the heat added to, or removed from, the system.
Answer:
The frequency
Step-by-step explanation:
The formula for the energy of an electromagnetic wave is
E = hf Thus,
E ∝ f and
f ∝ E
Answer:
LiCl - pink
NaCl - yellow
KCl - purple/blue-violet
CaCl₂ - orange/orange-red
Hope this helps.
Answer: Option (D) is the correct answer.
Explanation:
The chemical reaction equation will be as follows.

This means a new substance has been formed and a chemical change has taken place.
A chemical reaction in which heat energy is absorbed by the reactant molecules is known as an endothermic reaction.
For example,
On the other hand, a chemical reaction in which heat energy is released by the reactant molecules is known as an exothermic reaction.
For example,
is an exothermic reaction.
Thus, we can conclude that in the given situation the beaker most likely felt warm because a chemical reaction was producing a new substance.
