there is 1000 grams in 1 kilogram
Divide
80/1000 = 0.08
0.08 kilograms is your answer
hope this helps
There you go again. Newton's 3rd Law says "for every action there is an EQUAL OPPOSITE reaction.".
EQUALand OPPOSITE
If THIS MUCH force pushes the bullet THAT way, then THE SAME amount of force pushes the rifle THIS way.
The bullet pushes backward on the rifle with the same amount of force as the rifle exerts on the bullet.
at a distance of 0.2m for m the equilibrium position.
Answer:
a) 12.8 N
b) 3.2 m/s²
Explanation:
I'm guessing the period is 0.5π s.
Period of a spring in simple harmonic motion is:
T = 2π √(m/k)
Given T = 0.5π and m = 2 kg:
0.5π = 2π √(2/k)
0.25 = √(2/k)
0.0625 = 2/k
k = 32
The spring constant is 32 N/m, and the maximum displacement is 0.4 m. The maximum force can be found with Hooke's law:
F = kx
F = (32 N/m) (0.4 m)
F = 12.8 N
The acceleration can be found with Newton's second law:
∑F = ma
kx = ma
(32 N/m) (0.2 m) = (2 kg) a
a = 3.2 m/s²
Energy from an outside source is continuously being added
B.
The reaction container always feels cold.
C.
The reactants have more heat energy than the products.
D.
More heat is given off than is put into the reaction.
The statement which is true about exothermic reactions is as follows:
Thus, the correct option for this question is C.
An exothermic reaction may be defined as a type of reaction in which energy is significantly liberated in the form of heat or light. In such types of reactions, energy is generally transferred into the surroundings rather than utilized from the surroundings.
The option "energy from an outside source is continuously being added" represents an endothermic reaction in which heat or light energy is externally been provided. The option "more heat is given off than is put into the reaction" is not absolutely true because exothermic reactions liberate energy but it does not matter if it is higher or lower than that of being put into the reaction.
Therefore, the reactants have more heat energy than the products is a statement that is true about exothermic reactions. Thus, the correct option for this question is C.
