Answer:

10m/s

Explanation:

using the formula a=v-u

t

Answer:

Below

Explanation:

We can use this formula to find the final velocity of the object :

     vf = vi + at

Now, because no force is applied to the object, the acceleration of this object will be 0 according to Newton's 1st law!

     vf = 5m/s + (0)(5)

     vf = 5 m/s

Hope this helps!

Answer:

-Increase in temperature: increase

-Decrease in temperature: decrease

-Increase in volume: increase

-Decrease in volume: decrease

-Increase in pressure: increase

-Decrease in pressure: decrease

Explanation:

-Increase in temperature:

● Molecules gain kinetic energy and move fast thus increasing distance

-Decrease in temperature:

● Kinetic energy of molecules decrease so they have smaller distance

-Increase in volume:

● Molecules have more space to move around so distance increase

-Decrease in volume:

● Less space, molecules collide with each other because of decreased distance thus increasing pressure

-Increase in pressure

● Molecules collide with each other and the walls of container increasing pressure so molecules move faster and it increases distance

-Decrease in pressure:

● Molecules collide with each other and walls of container less frequently so distance between molecules decrease

Answer:

the correct answer will be 6.82 %that is 7%

p(1.27)-q(0.83) =x=0.44

0.02+0.01 =0.03 (maximum uncertainty)

percentage uncertainty =0.03/0.44×100 %

=6.82%

=7%

Answer: I think cars are designed to have crumble zone because lets say you're going 60-70 mph and you hit a brick wall that cant move, it would be a very hard jolt causing the beings inside to get thrown forward, but if it has a crumble zone it would slow the the jolt from is slowing down in the hit.

Where's the diagaram?

The magnitude of the adhesive force allows the top block to remain

attached to the bottom when the blocks and the wire are balanced.

The option that must be true is; [tex]\mathbf{W_{bottom} = F_{adhesion}}[/tex]

Reason:

The tension exerted by the wire attached to the top block = T

Magnitude of the adhesive = [tex]F_{adhesion}[/tex]

Weight of the top block = [tex]W_{top}[/tex]

Weight of the bottom block = [tex]W_{bottom}[/tex]

Given that with the exertion of the tension, the two blocks remain at rest, we have;

The adhesive causes the bottom block to remain attached to the top block, we have;

Therefore, the magnitude of the adhesive force adds the bottom weight, to the top, weight, which gives;

The magnitude of the adhesive force = The weight of the bottom block

Therefore;

Explanation:

The coefficient of kinetic friction between the chair and the floor is 0.442.

The given parameters;

The normal force on the chair is calculated as follows;

Fₙ = mg

Fₙ = 30 x 9.8 = 294 N

The frictional force between the chair and the floor is calculated as follows;

Fk = μFₙ

The net force on the chair is calculated as follows;

[tex]\Sigma F_x = 0\\\\F- \mu_k F_n = 0\\\\130 - \mu_k (294) = 0\\\\\mu_k = \frac{130}{294} \\\\\mu_k = 0.442[/tex]

Thus, the coefficient of kinetic friction between the chair and the floor is 0.442.

Explanation:

Position is the location of the object (whether it's a person, a ball, or a particle) at a given moment in time.

Displacement is the difference in the object's position from one time to another.

Distance is the total amount the object has traveled in a certain period of time.

Answer:

~186

Explanation:

1) R= (V^2 × sin A ) /g

V=90 m/a

A= 13°

g= 9.8 or 10 (I will take 9.8 for right result)

R= (90^2 × sin 13) / 9.8 = 185.928932672 ~ 186
