To calculate g, we use the formula F= mg. F is given as 180N, and m is given as 30 kg, therefore:
180N = (30kg)(g)
g = 6 m.s-1.
The motion of this object would be decreased on Earth as more force would be required to lift it. If we assume g is 9.8 m.s-1 on Earth, we can calculate the force required.
F = mg
= (30kg)(9.8 m.s-1)
= 294 N
Answer:
21 3/4
Step-by-step explanation:
3 times 7 1/4 since the scale is 1:7 1/4. Good luck!! :)

Answer:
= 85
Step-by-step explanation:
given m = - 2, and n = -4
Substitute the given values into the polynomial expression:
![[(-2)^{4} + 5] - (-4)^{3}](https://tex.z-dn.net/?f=%5B%28-2%29%5E%7B4%7D%20%2B%205%5D%20-%20%28-4%29%5E%7B3%7D)
= (16 + 5) - (-64)
= 21 + 64
= 85
Therefore, the correct answer is 85.
