Combine like terms.
7g + 4g + 3g + g = 15g
15g - 13g = 2g
2g = 10
Divide by 2 on both sides.
g = 5
Answer:
8 Joule
Step-by-step explanation:
Mass of block = 2 kg
Displacement = x = 800 mm = 0.8 m
Spring constant = k = 25 N/m
Potential Energy of a spring
Work done = Difference in Potential Energy
Work Done = Δ P.E.

⇒P.E. = 0.5×25×0.8²
⇒P.E. = 8 Nm = 8 Joule
Here already the spring constant and displacement is given so the mass will not be used while calculating the potential energy.
Answer:
All you need to remember is the rules
Step-by-step explanation:
Let us remember
a to the m power x a to the nth power is = a to the m+n power. (add the exponents)
And
a to the m power ÷ a to the nth power is = a to the m-n power. (subtract the exponents) So
14 to the -4 power x 14 to the 7 power= 14 to the -4+7 which is equal to 14 to the 3rd power
Answer:
3 jeans and 5 sweaters
Step-by-step explanation:
This is a solid guess
However, this is a straight forward question.
175 she has to spend all of it.
To make it an even number you minus 25.
Than you have 150, minus another 50.
You have 5 more clothes to buy, and $100 left.
You use the rest to buy sweaters, therefore spending all the money and getting 8 clothing.
As x approaches -inf f(x) -> -inf
and as x approaches inf, f(x) approaches +inf
