<span>You are given an applied force of 110 n with an angle of 30</span>°<span> with the ground. Since the  force is not perpendicular or parallel to the sled then you will have two components. These components are in sine and cosine form.

for parallel component
x = rcos</span>β
<span>x = 110cos30</span>°
<span>x = 95.26

for the perpendicular component
y = rsin</span>β
<span>y = 110sin30</span>°
<span>y = 55</span>

Explanation:

It is given that,

Force exerted on the sled, F = 110 N

The angle force makes with the ground is 30 degrees.

There are two components of force i.e. the parallel and perpendicular components. They are termed as F_x\ and\ F_y

Parallel component :

F_x=F\ cos\theta

F_x=100\ cos(30)

F_x=86.6\ N

Perpendicular component :

F_y=F\ sin\theta

F_y=100\ sin(30)

F_y=50\ N

So, the parallel and perpendicular components of this force with respect to the ground are 86.6 N and 50 N respectively. Hence, this is the required solution.

A 91-kg astronaut and a 1300-kg satellite are at rest relative to the space shuttle. The astronaut pushes on the satellite, givi
WARRIOR [948]

Answer:

18.2145 meters

Explanation:

Using the conservation of momentum, we have that:

m1v1 + m2v2 = m1'v1' + m2'v2'

m1 = m1' is the mass of the astronaut, m2=m2' is the mass of the satellite, v1 and v2 are the inicial speed of the astronaut and the satellite (v1 = v2 = 0), and v1' and v2' are the final speed of the astronaut and the satellite. Then we have that:

0 + 0 = 91*v1' + 1300*0.17

v1' = -1300*0.17/91 = -2.4286\ m/s

The negative sign of this speed just indicates the direction the astronaut goes, which is the opposite direction of the satellite.

If the astronaut takes 7.5 seconds to come into contact with the shuttle, their initial distance is:

distance = 2.4286 * 7.5 = 18.2145\ meters

If m=120kg and a=15m/s2, what is the force
Scorpion4ik [409]

Answer:

F= 1800N

Explanation:

the equation for force is F= ma

so plug in the numbers: F= (120)(15)

solve this to get F= 1800N

tip: don't forget to add the units when writing your answer :)

An object is 1.0 cm tall and its erect image is 5.0 cm tall. what is the exact magnification?
ikadub [295]
The exact magnification of the objects is calculated by dividing the cinema. We calculate it by diving the erect image size by the object size. From the given above, we find the exact magnification by dividing 5.0 cm by 1.0 cm. Thus, the answer would be 5.

if the radius of the capillary tube is doubled, what changes will take place in the hieght of rise of liquid with capacity tube
tangare [24]

Explanation:

The height of the rise of liquid with capillary tube is given by the formula as follows :

h=\dfrac{2S\cos\theta}{r\rho g}

Where

r is radius

It is clear that the height of the rise of liquid is inversely proportional to the radius of the capillary tube.

If the radius of the capillary tube is doubled, it means the height of rise of liquid with capillary tube become half.
