Answer:
5.49×10⁻⁴ lbm
Explanation:
Convert volume to m³.
V = (200 cm³) (1 m / 100 cm)³ = 0.0002 m³
Find mass in kg.
m = ρV
m = (1.24507 kg/m³) (0.0002 m³)
m = 0.000249 kg
Convert mass to lbm.
m = (0.000249 kg) (2.205 lbm/kg)
m = 0.000549 lbm
m = 5.49×10⁻⁴ lbm
Answer:
When he weight of the car is 8.55 x 
N then power = 314.012 KW
When he weight of the car is 1.10 x 
N then power = 43.76 KW
Explanation:
Given that
Initial velocity 
= 0
Final velocity 
= 24.8 
Time = 7.88 sec
We know that power required to accelerate the car is given by
P = 
Change in kinetic energy Δ K.E = 
Since Initial velocity = 0
⇒ Δ K.E = 
⇒ Power P = 
⇒ Power P = 
-------- (1)
(a). The weight of the car is 8.55 x N = 8550 N
Put all the values in above formula
So power P = 
P = 314.012 KW
(b). The weight of the car is 1.10 x N = 11000 N
Put all the values in equation (1) we get
P = 
P = 43.76 KW
If the Earth's core cools down, then one of the first things that would happen is that plate tectonic activity would slow down. Over time, the Earth would then dry up into this ball of dry soil because the heat of the Earth's core drives water up to the surface. Since the crust would be void of majority of liquid, it would shrink by an unknown amount.
It depends on the length of the pendulum and the strength of gravitational pull acting upon the pendulum.
Hope this helps!
