F1x + F2x = Rx

↓

Rx = F1x + F2x

↓

Rx = F1 cos45° + F2

↓

Rx = (50N)(cos45°) + 60N

↓

Rx = 95N

Similarly, if we sum all the y components, we will get the y component of the resultant force:

F1y + F2y = Ry

↓

Ry = F1y + F2y

↓

Ry = F1 sin45° + 0

↓

Ry = F1 sin45°

↓

Ry = (50N)(sin45°)

↓

Ry = 35N

At this point, we know the x and y components of R, which we can use to find the magnitude and direction of R:

Rx = 95N

Ry = 35N

Which are characteristics of a gas? (Select all that apply.)It cannot move.It fills the container it is in.It can be compressed.

Aleonysh [2.5K]

Answer: no definite shape (takes the shape of its container)

no definite volume.

particles move in random motion with little or no attraction to each other.

highly compressible.

Explanation:

Gases have three characteristic properties: (1) they are easy to compress, (2) they expand to fill their containers, and (3) they occupy far more space than the liquids or solids from which they form.

A merry-go-round makes one complete revolution in 5.3 s. A 48.5 kg child sits on the horizontal floor of the merry-go-round 2.7

Marianna [84]

Answer:183.94 N

Explanation:

Given

Time Period $T=5.3 s$

mass of child $m=48.5 kg$

Radius $r=2.7 m$

Velocity $v=\frac{2\pi \cdot r}{T}$

$v=\frac{2\pi \cdot 2.7}{5.3}$

$v=3.20 m/s$

Now Centripetal Force will be Balanced by Frictional Force

Centripetal Force $F_c=m\cdot \frac{v^2}{r}$

$F_c=48.5\cdot \frac{3.2^2}{2.7}$

$F_c=183.94 N$

therefore Friction Force is 183.94 N

3. The function of the _______ is to convert the up-and-down motion of the piston into rotary motion that can be used to power t

DENIUS [597]

The function of the crankshaft is to convert the up-and-dwon motion of the piston into rotary motion that can be used to power the vehicle.

I attache an image of a crankshaft.

The pistons are connected to the crank pins ans when the pistons move up an down the crankshaft rotate, and so the recoprating movement of the pistons is converted into rotary motion.
