100N force is applied to a ball with a mass of 0.25kg. Calculate the ball acceleration.

The statement which fairly compares segment 2 and segment 3 is These represent equal periods of time, but the force during segment 2 is different than the force during segment 3.

Since segment 2 starts at t = 60 s and ends at t = 150 s, the time interval is Δt = 150 - 60 = 90 s.

Also, segment 3 starts at t = 150 s and ends at t = 240 s, the time interval is Δt = 240 - 150 = 90 s.

So, their time periods are the equal.

We notice that segment 2 is less steep than segment 3 this implies that the acceleration in each segment is different, since the acceleration is the slope of the graph.

Since force is determined by acceleration, this implies that the force on segment 2 is different form the force acting in segment 3.

So, we have equal time periods but different forces.

So, the statement which fairly compares segment 2 and segment 3 is These represent equal periods of time, but the force during segment 2 is different than the force during segment 3.

Answer: no change in volume

Explanation:

Hi there!

Since the ball is thrown with an initial HORIZONTAL velocity, we can treat this as a free-fall situation since the horizontal motion does NOT impact the ball's vertical motion.

We can use the derived kinematic equation:

[tex]t = \sqrt{\frac{2h}{g}}[/tex]

Plug in the given values:

[tex]t = \sqrt{\frac{2(150)}{9.8}} = \large\boxed{5.53 s}}[/tex]

The angle of projection is 0° because there is no vertical component to the velocity as the initial velocity is purely horizontal.

Range:

We can use the equation:

dₓ = vₓt

displacement (x direction) = velocity (x direction) · time

Used the solved-for time and given velocity:

dₓ = 100 · 5.53 = 553 m

kinetic energy equation is 85,714.2857 kg.

Explanation:

This question involves the concepts of potential difference, inductance, and current.

The minimum time that should be allowed for the current to change is "0.694 ms".

The inductance of an inductor is given by the following formula:

[tex]E=L\frac{\Delta I}{\Delta t}\\[/tex]

where,

E = potential difference across the inductor = 360 volts

L = inductance of the inductor = 250 mH = 0.25 H

ΔI = change in current = 2.5 A - 1.5 A = 1 A

Δt = time required = ?

Therefore,

[tex]\Delta t = \frac{(0.25\ H)(1\ A)}{360\ volts}[/tex]

Δt = 6.94 x 10⁻⁴ s = 0.694 ms

Hi there!

We can use the following equation (Newton's Second Law):

∑F = ma

m = mass of object (kg)

a = acceleration (m/s²)

We can rearrange to solve for 'a':

F/m = a

Remember to convert grams to kg.

1000g = 1 kg

0.035/(0.0114) = 3.07 m/s²

Answer:

Explanation:E=mgh=25×4×10=1000J

Answer:

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question

mass = 2.5 kg

acceleration = 3.0 m/s²

We have

force = 2.5 × 3.0 = 7.5

Explanation:

Doubling the mass of the Earth would double your weight, since gravitational force is directly proportional to mass, but doubling the radius (which doubles if the diameter doubles) would decrease your weight by a factor of 1/4, since gravitational force is inversely proportional to the square of the radius.

Explanation:

France is the undisputed champion in the world of skiing.

The white disk has a larger radius.

We know that the speed of the coin v = rω where r = radius of the disk and ω = angular speed of the disk.

Now, since both disks rotate at constant speed, ω = constant.

So, v ∝ r

For the black disk, its radius is r, the coins speed is v.

For the white disk, let its radius be R, the coins rotates at a speed V = 4v

We know that v ∝ r.

Since the coin on the white disk has a greater speed, so its radius would be greater.

So, the white disk has a larger radius.

The number of heaters that can safely be operated in the circuit is 5 heaters.

From the question given above, the following data were obtained:

Power of heater = 300 W

Voltage (V) = 110 V

Current (I) = 15 A

Voltage (V) = 110 V

Current (I) = 15 A

P = IV

P = 15 × 110

Thus, the power that can be drawn from the circuit is 1650 W

Power of heater = 300 W

Power of Circuit = 1650 W

[tex]Number \: of \: heaters \: = \frac{power \: of \: circuit}{power \: of \: heater} \\ \\ = \frac{1650}{300} \\ \\ = 5.5[/tex]

Hi there!

We know that:

U (Potential energy) = mgh

We are given the potential energy, so we can rearrange to solve for h (height):

U/mg = h

g = 9.81 m/s²

m = 30 g ⇒ 0.03 kg

0.062/(0.03 · 9.81) = 0.211 m
