Answer:
49N
Step-by-step explanation:
Step one
Given
When the force of 63 N acts on a certain object
the acceleration of the object is 9/ms^2
Firstly, we need to calculate the mass m
F=ma-------1
m= F/a
m= 63/9
m= 7kg
Step two:
Also, if the acceleration of the object becomes 7 m/s^2
then the force
Note: the mass remains the same= 7kg
F=ma
F=7*7
F= 49N
Answer:
Wilhem
Step-by-step explanation:
The given equation is

Step 1 : Add 32g and 8g.



Step 2: Subtract 10 from 40.


Step 3: Divide both sides by 30, find the value of g.


The value of g is 5.
Therefore, Wilhem is correct.
Depending on how heavy the package is, you should take the Fed Ex if the package is heavy, and the UPS for something that is small
You would round 1506 to 1500 and and do not round 2. So then you woulddo 1500 divided by 2 to get 750!
