Answer:

the initial velocity of the particle is 5 cm/s

Explanation:

Given initial displacement as, s = 6t² + 5t - 5

s is measured in "cm"

t is measured in "seconds"

Velocity is the rate of change of displacement with time. Expressed as follows;

[tex]v = \frac{ds}{dt} = 12t + 5[/tex]

for initial velocity, time (t) = 0

v = 12(0) + 5

v = 5 cm/s

Therefore, the initial velocity of the particle is 5 cm/s

Answer:

the answer is B. 70 x 10-6 m

Explanation:

i'm doing the test rn

When converting from micrometers to meters, you have to divide the value by 1,000,000

= 70/1000000

= 7 ×10⁻⁵

Hence the thickness of the human hair is in meters is 7×10⁻⁵ m

Answer:

Explanation:

Answer:

The waves travel at the same speed, but the observed frequency depends on any relative motion between the observer and source. When the observed frequency changes, so does the wavelength. If the observer and source are moving toward each other, then the frequency increases and the wavelength decreases

Answer:

As The mass of the beach ball is having lowest magnitude when compared with the other balls given so when apply the same magnitude of force to all the balls then the beach ball due to its lighternessand also its inertia of rest would not resist the force so much so when you apply the force to this ball it would starts to roll and covers the maximum diatance whwn compared with the other ball only in the condition when same magnitude of force applied.Thats this ball would do more work than the other ball.The mass also influences the velocity carried by the body and also the kinetic energy possessed by the body. More the force applied more the distance it would cover

Answer:

Rotational inertia depends both on an object's mass and how the mass is distributed relative to the axis of rotation. ... We can't just consider the mass to be concentrated at its center of mass. When a mass moves further from the axis of rotation it becomes more difficult to change the rotational velocity of the system.So the ball with 10 pounds of the ball can have more probability to do an absolute pure rotation along rolling translation.And also the specific material from which it is made up of. As If the body is rigid have the points dont move from their position when a magnitude of force applied then the body woukd perform a well rotation than a resistantant body.

Answer:

E) 147 V

Explanation:

Ra+Rb+Rc = 14.0

V = IR

V = (10.5)(14.0)

V = 147 V

The potential difference across the source will be c)12V

Ohm's law states that  the current through a conductor between two points is directly proportional to the voltage across the two points .

since , R(A) , R(B) AND R(C) are in parallel combination , hence  equivalent

resistance of the circuit will be

1/R = 1/R(A) + 1/ R(B) + 1/ R(C)

1/R= 1/2 + 1/4 +1/8

1/R = 7/8

R = 8/7 ohm

from ohm's law

Voltage = current * resistance

V( source ) = current (in circuit ) * R (equivalent resistance)

V = 10.5 * (8/7)

V = 12 V

The potential difference across the source will be c) 12V

Answer:

As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases.

Answer:

37.5 seconds

Explanation:

The given parameters are;

The mass of the block on the spring, m = 2.50 kg

The force with which the loaded spring launches the block, F = 450 N

The change in momentum of the block, Δp = 12.0 kg·m/s

We have;

Let the force with which the block was launched = The net force, [tex]F_{NET}[/tex]

By Newton's second law of motion, we have;

F = [tex]F_{NET}[/tex] = Δp × Δt

Where;

Δt = The time the block is in contact with the spring

Therefore;

[tex]\Delta t = \dfrac{F_{NET}}{\Delta p}[/tex]

By plugging in the values for [tex]F_{NET}[/tex] and Δp, we have;

[tex]\Delta t = \dfrac{450 \ N}{12.0 \ kg \cdot m/s} = 37.5 \ s[/tex]

The time duration the block is in contact with the spring, Δt = 37.5 seconds.

Answer:

R = 1000 ohm

Explanation:

In a circuit with a resistor R, the current is

           V = i R

            i₀ = V / R

a resistor R₁ is placed in parallel and the current is tripled i = 3 i₀

           V = i Req

            i = V / Req

           3i₀ = V / Req

we substitute

           3 (V / R) = V / Req

           3 / R = 1 / Req

           R = 3 Req

the equivalent resistance of the two resistors in parallel is

            [tex]\frac{1}{R_{eq}} = \frac{1}{R} + \frac{1}{R_1}[/tex][tex]\frac{1}{R_{eq}} = \frac{R_1 + R}{R \ R_1}[/tex]

              R_{eq} = [tex]\frac{R \ R_1}{R + R_1}[/tex]

              R / 3 = \frac{R \ R_1}{R + R_1}

              ⅓ (R₁ + R) = R₁

              R = 3R₁ -R₁ = 2 R₁

              R = 2 500

              R = 1000 ohm

Explanation:

Kinetic energy is the energy which a body possesses by virtue of being in motion. Thus, kinetic energy is the energy of motion.

In physics, an object's kinetic energy is the energy it has as a result of its motion. It is defined as the amount of work required to accelerate a body of a given mass from rest to a given velocity. The standard unit of kinetic energy is the joule. Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass.

The body retains its kinetic energy after gaining it during acceleration unless its speed changes. The body does the same amount of work when slowing down from its current speed to rest.

Therefore, kinetic energy is the energy of motion.
