Answer:

[tex]a=0.8\ m/s^2[/tex]

Explanation:

Given that,

Mass of a toy, m = 0.62 kg

Horizontal force, F = 16.3 N

Force on the opposite direction, F' = 15.8 N

We need to find the acceleration of the toy.

Here, two forces are acting in opposite direction, the net force will be the difference of forces.

Net force = 16.3 N-15.8 N

=0.5 N

The formula for net force is given by :

F = ma

a is the acceleration of the toy

[tex]a=\dfrac{F}{m}\\\\a=\dfrac{0.5\ N}{0.62\ kg}\\\\a=0.8\ m/s^2[/tex]

So, the acceleration of the toy is [tex]0.8\ m/s^2[/tex].

In physics, tension is described as the pulling force transmitted axially by the means of a string, a cable, chain, or similar object, or by each end of a rod, truss member, or similar three-dimensional object.

According to the question, the formula we use in this method is F = ma as we have to find the acceleration.

Therefore, the formula for the acceleration is

[tex]a= \frac{F}{m}[/tex]

[tex]a= \frac{0.5}{0.62}[/tex]

Hence, after the calculation, the acceleration is 0.8m/s.

Answer:

[tex]\boxed {\tt 230.769231 \ seconds}[/tex]

Explanation:

Time can be found by dividing the distance by the speed.

[tex]t=\frac{d}{s}[/tex]

The distance is 9,000 meters and the speed is 39 meters per second.

[tex]d= 9,000 \ s\\s=39 \ m/s[/tex]

Substitute the values into the formula.

[tex]t=\frac{9,000 \ m}{39 \ m/s}[/tex]

Divide. Note that the meters, or "m" will cancel out.

[tex]t=\frac{9,000}{39 \ s}[/tex]

[tex]t=230.769231 \ s[/tex]

It takes 230.769231 seconds for the truck to travel 9,000 meters at 39 meters per second.

Answer:

increases

Explanation:

as we know, that submarines need to be really really strong to go down in the ocean. That means that the more they go down in the water (liquid) then, they will face more pressure. That as we said, that the more down they go, the more pressure will be on them, which means that the pressure will keep on increasing as you go down and down in the ocean.

The net force would be needed to accelerate a 2.95kg bowling ball at 6.25m/s^2 will be F = 18.4375 N

Newton's second law of motion  states that the time rate of change of the momentum of  a body is equal in both magnitude and direction to the force  imposed on it.

For a constant mass , force is equal to  Force = mass * acceleration

given

mass(M) = 2.95 kg

acceleration(a) = 6.25 m/s^2

Force(F)  = ?

Force(F) = mass(M) * acceleration(a)  (from Newton's second law of motion  )

F =  2.95 * 6.25

F = 18.4375 N

====================================================

Explanation:

Since we're not talking about points, but rather large areas/countries, this means that an absolute single location doesn't make much sense.

However, we can try to go for the middle-most part of the country if possible.

Spain's northernmost and southernmost boundaries are between the 30° and 45° latitude lines in the northern hemisphere. The country appears to be closer to 45° N rather than 30° N. A good estimate is maybe something like 42° N. Though like I said, there's going to be wiggle room here depending which point you use as the representative point of Spain. The larger the country, the more variation in possible answers.

At the same time, much of Spain appears to be between the Prime Meridian and the longitude line 15° W. I'll split the difference and get (0+15)/2 = 15/2 = 7.5 = 8.

Therefore, one estimate of Spain's absolute GPS location is 42° N and 8° W

The other countries are handled in a similar fashion.

The truck must travel at a speed of 98.6677 km/hr to stay beneath the airplane

Explanation:

The given parameters are;

The velocity of the airplane, v = 105 km/hr

The direction of the airplane, θ = 25 degrees to the ground = 25°

Therefore, we have that the horizontal component of the velocity of the plane, vₓ is given as follows;

vₓ = v × cos(θ) = 105 km/hr × cos(25) ≈ 98.6677 km/hr

The vertical component of the velocity of the plane, [tex]v_y[/tex], is given as follows;

[tex]v_y[/tex] = v × sin(θ)  = 105 km/hr × sin(25) ≈ 44.37 km/hr

The truck only has to travel at a speed equal to the horizontal velocity of the airplane to stay beneath the airplane

Therefore, the travelling speed the truck must be vₓ which is 98.6677 km/hr to stay beneath the airplane.

The kinetic energy refers to energy in motion. The moving dart possesses kinetic energy. From the calculations, the speed of the dart after it is thrown is 13 m/s.

The term energy refers to the ability to do work. We must note that work done is throwing the dart is equal to the kinetic energy of the moving dart once it is thrown.

If work done = kinetic energy = Fx

Where;

F =  force

x = distance

W =  4.40 N * 0.54 m = 2.376 J

Now;

KE = 1/2 mv^2

m = mass of the dart

v = velocity of the dart

Answer:

D) A car requires more applied force to move on wet pavement

Explanation:

The coefficient of friction determines the frictional force that the ground applies on the car .

Maximum force of friction generated = μ R where μ is coefficient of friction and R is reaction force of the ground

Reaction force of the ground = mg or weight of the car . Since weight is same on dry and wet ground so normal force will be same is both the case .

Force of friction generated in respect of dry pavement will be more because of greater coefficient of friction .

Friction force helps in driving a car in forward direction hence it is easy to drive car on dry pavement . On wet pavement , it will slip off at the same place rather than move forward .

Answer:

The distance by which the child is safe is  [tex]k = 10 \ m[/tex]

Explanation:

From the question we are told that

  The speed of the motorcycle is  [tex]v_n = 30 m/s[/tex]

   The distance of the child from the motorcycle is L =  190 m

    The reaction time is  [tex]t_r = 1 \ s[/tex]

    deceleration is  [tex]a = -3m/s^2[/tex]

Generally the distance covered during the reaction time is  

    [tex]D = v_n * t_r[/tex]

=>[tex]D = 30 * 1[/tex]

=> [tex]D = 30 \ m[/tex]

Generally the distance covered during the deceleration

     [tex]v^2 = u^2 + 2as[/tex]

Here v is the final velocity which is  zero  

So

   [tex]0 = 30 ^2 + 2 * (-3)s[/tex]

=> [tex]s = 150 \ m[/tex]

So the total distance the motorcycle rider will cover before coming to rest is  

     [tex]d = D + s[/tex]

=>   [tex]d = 30 + 150[/tex]

=>  [tex]d = 180 \ m[/tex]

Therefore the amount of distance by which the child id safe is  

    [tex]k = L -d[/tex]

=> [tex]k = 190 -180[/tex]

=>  [tex]k = 10 \ m[/tex]

By knowing that the total charge must remain constant, we will see that:

c)

d)

If these are conductor spheres, we can assume that the charge flows through the spheres.

So, when two touches, the charge tries to equilibrate.

When sphere B and sphere C touch, the total charge between them would be equally distributed between the two spheres.

Charge B = -8.0 C

Charge C = +9.0 C

Total = -8.0 C + 9.0 C = 1.0 C

half of that is 0.5 C

Then now both sphere B and sphere C will have 2.5C each.

And sphere A still has the -4.0 C

Then the total of the 3 spheres is:

0.5C + 0.5C - 4.0C = -3.0C

The total charge never changes in a closed system, remember that.

D) Similar to before, this time the total charge will be equally distributed among the 3 spheres.

The total charge is -3.0C

So:

And the total charge will be:

-1.0 C + -1.0 C + -1.0 C = -3.0C

Explanation:

The acceleration of an object is equal to the rate of change of velocity. Its mathematical form is given by :

[tex]a=\dfrac{v-u}{t}[/tex]

Where

v is final velocity, u is initial velocity and t is time taken

The SI unit of velocity is m/s and that of time is s. The SI unit of acceleration is [tex]\dfrac{m/s}{s}=m/s^2[/tex]

If final velocity is more than the initial velocity, acceleration is positive.

If the final velocity is less than the initial velocity, the acceleration is negative. It is also known as deceleration.

Hence, all the statement is true.
