We know, density = mass / volume
Here, d = 8.5 g/cm³
v = 2 * 5.4 * 3.1 = 33.48 cm³

Substitute their values, 
m = 8.5 * 33.48
m = 284.58 g

In short, Your Answer would be 284.58 g

Hope this helps!

It is true that only half of the moon is always illuminated by the sun.  The reason why the moon changes it phases is because Moon orbits around the Earth, and due to this some areas of the half of the moon will not be lit by the sun.

Otrada [13]

Answer: 114 km/h

Explanation:

The formula for determining average speed is expressed as

Average speed = total distance/total time

The car travels 85 km in the first half hour of a trip. The car continues to travel for 2 more hours and travels 200 km. It means that the total distance that the car travels is

85 + 200 = 285 km

The total time spent by the car is

0.5 + 2 = 2.5 hours

Therefore,

Average speed = 285/2.5 = 114 km/h

Lemur [1.5K]

Answer:

1.7\cdot 10^3 N

Explanation:

The impulse theorem states that the product between the force and the time interval of the collision is equal to the change in momentum:

F \Delta t = m \Delta v

where

F is the force

\Delta t is the time interval

m is the mass

\Delta v is the change in velocity

Here we have

m = 84 kg

\Delta t = 1.2 s

\Delta v = 24 m/s

So we can solve the equation to find the force:

F= \frac{m \Delta v}{\Delta t }=\frac{(84 kg)(24 m/s)}{1.2 s}=1680 N \sim 1.7\cdot 10^3 N
