Option B) 10m/s² is the correct answer.

Hence, the acceleration of the new sports car in the given period of time is 10m/s².

What is Motion?

Motion is simply the change in position of an object over time.

From the First Equation of Motion;

v = u + at

Where v is final velocity, u is initial velocity, a is acceleration and t is time elapsed.

Given the data in the question;

Initial velocity of the sport car u = 0m/sFinal velocity of the sport car v = 120m/sElapsed time t = 12sAcceleration of the sports car a = ?

To determine the acceleration of the new sports car, we substitute our given values into the expression above.

v = u + at

120m/s = 0m/s + (a × 12s)

a × 12s = 120m/s - 0m/s

a × 12s = 120m/s

a = 120m/s ÷ 12s

a = 10m/s²

Option B) 10m/s² is the correct answer.

Hence, the acceleration of the new sports car in the given period of time is 10m/s².

When an element ejects an alpha particle, the mass number of that element

A.reduce by 4.

B.remains unchanged.

C.increase by 1.

D. reduce by 1.

Answers

Answer:

A.reduce by 4.

Explanation:

In Chemistry, an alpha particle which is typically a helium nucleus has an atomic mass (number of nucleons) of four (4). Therefore, the ejection of an alpha particle by any chemical element simply means that, the mass number of that particular chemical element would be reduced by four (4).

Basically, this process is referred to as an alpha decay and can be defined as a radioactive disintegration of a chemical element that causes it to emit an alpha particle and as a result reducing its mass number by four (4).

Hence, when an element ejects an alpha particle, the mass number of that element reduces by 4.

Answers

Answer:

C) 0.00026 Hz

Explanation:

In any wave, there exists a fixed relationship between the speed v, the frequency f and the wavelength λ, as follows:

       [tex]v = \lambda * f (1)[/tex]

Replacing by the givens in (1), and solving for f, we get:

       [tex]f = \frac{v}{\lambda} = \frac{700km/hr}{750 km} = 0.93 1/hr (2)[/tex]

Converting the units to Hz (1/sec), we get:

A police officer standing at the side of the road uses a radar emitting frequency of 24.15 GHz. A car is going away from the officer at a speed of 50mph. What will be the difference in frequency of the beam reflected by the car received back by the radar?
a. 4.0 kHz (lower frequency)
b. 1.8 kHz (higher frequency)
c. 4.0 kHz (higher frequency)
d. 1.8 kHz (lower frequency)

Answers

Answer:

The correct answer is  C

Explanation:

  From the question we are told that  

       The frequency of the radar is [tex]f = 24.15 \ GHz = 24.15 *10^{9} \ Hz[/tex]

         The speed of the car is [tex]v = 50 mph = \frac{50}{2.237} = 22.35 \ m/s[/tex]

Generally the difference frequency reflected by the car and the frequency which the radar receives back is mathematically represented as

        [tex]\Delta f = \frac{f * 2 * v }{ c }[/tex]

Here  c is the speed of light with value  [tex]c = 3.0 *10^{8} \ m/s[/tex]

=>    [tex]\Delta f= \frac{2 * 24.15 *10^{9} * 22.35}{ 3.0*10^{8}}[/tex]      

=>    [tex]\Delta f = 4000 \ Hz[/tex]

=>     [tex]\Delta f = 4.0 \ kHz[/tex]

A disk rotates at a constant angular velocity of 30 degrees per second. Consider a point on the edge of the disk. Through how many degrees has it rotated after 3 seconds?

Answers

Answer:

The disk covers a rotation of 90º after 3 seconds.

Explanation:

Since the disk rotates at constant angular speed, we can determine the change in angular position ([tex]\Delta \theta[/tex]), measured in sexagesimal degrees, by the following kinematic formula:

[tex]\Delta \theta = \omega\cdot \Delta t[/tex] (1)

Where:

[tex]\omega[/tex] - Angular velocity, measured in sexagesimal degrees per second.

[tex]\Delta t[/tex] - Time, measured in seconds.

If we know that [tex]\omega= 30\,\frac{\circ}{s}[/tex] and [tex]\Delta t = 3\,s[/tex], then the change in angular position is:

[tex]\Delta \theta = \left(30\,\frac{\circ}{s} \right)\cdot (3\,s)[/tex]

[tex]\Delta \theta = 90^{\circ}[/tex]

The disk covers a rotation of 90º after 3 seconds.

Answers

Answer:

A & D your welcome

Propanol surface is more flattered and has less boiling point than that of water.

To determine the correct statements among all the statements, we need to know about the surface tension.

What is surface tension?Surface tension is defined as force per unit length.More the surface tension, more the force between the molecules to keep the molecules together.What does happen, if molecules have more force of attraction?If the molecules have large force of attraction, more heat will be required to break the bonds between them. So the boiling point increases. Also with more force of attraction, the surface of the liquid becomes less flattered.

Since, propanol has less surface tension than that of water, so its surface is more flattered and has less boiling point than that of water.

For an n- channel JFFT, IDSS = 8 mA, and VP = - 6 V. If VGS = - 2 V. What is the value of the drain current ID?

Answers

Answer: the value of the drain current ID is 3.56 mA

Explanation:

Given that;

IDSS = 8 mA

VP(VGS_OFF) = - 6 V.

VGS = - 2 V

value of the drain current ID = ?

Drain current ID is expressed as;

ID = IDSS [ 1 - (VGS/VP(VGS_OFF)) ]²

we substitute our value

ID = 8 [ 1 - (-2 / -6) ]²

ID = 8 [ 1 - 0.3333 ]²

ID = 8 [ 0.6667 ]²

ID = 8 [ 0.4444 ]

ID = 3.5552 ≈ 3.56 mA

Therefore the value of the drain current ID is 3.56 mA

An astronaut stands on the surface of an asteroid. The astronaut then jumps such that the astronaut is no longer in contact with the surface. The astronaut falls back down to the surface after a short time interval. Which of the following forces CANNOT be neglected when analyzing the motion of the astronaut?

Answers

Asteroids are known through the help of artificial gravity, to have small gravity. The forces that cannot be neglected when analyzing the motion of the astronaut is that the gravitational force between the astronaut and the asteroid.

The gravitational force between two objects is said to be inversely proportional to the distance between them when squared. Therefore, when an individual halve the distance then the force increases by four times.

Unbalanced forces are simply known to be brought about due to a change in motion, speed, and/or direction. If two forces act in the same direction on an object, the net force is said to be equal to the sum of the two forces.

A 1.2-kg object moving with a speed of 8.0 m/s collides perpendicularly with a wall and emerges with a speed of 6.0 m/s in the opposite direction. If the object is in contact with the wall for 2.0 ms, what is the magnitude of the average force on the object by the wall?
a. 9.8 kN.
b. 8.4 kN.
c. 7.7 kN.
d. 9.1 kN.
e. 1.2 kN.

Answers

Given that,

Mass of the object, m = 1.2 kg

Initial speed of the object, u = 8 m/s

Final speed of the object, v = -6 m/s (in opposite direction)

Time, t = 2 ms

To find,

The average force on the object by the wall.

Solution,

Let F be the force. Using Newton's second law of motion,

F = ma, a is acceleration

[tex]F=\dfrac{m(v-u)}{t}\\\\F=\dfrac{1.2\times ((-6)-8)}{2\times 10^{-3}}\\\\=8400\ N[/tex]

A 10.0kg object is moving at 1 m/s when a force is applied in the direction of the objects motion, causing it to speed up to 4 m/s. If the force was applied for 5s what is the magnitude of the force

Answers

Answer:

F = 6[N].

Explanation:

To solve this problem we must use the principle of conservation of linear momentum, which tells us that momentum is conserved before and after applying a force to a body. We must remember that the impulse can be calculated by means of the following equation.

[tex]P=m*v\\or\\P=F*t[/tex]

where:

P = impulse or lineal momentum [kg*m/s]

m = mass = 10 [kg]

v = velocity [m/s]

F = force [N]

t = time = 5 [s]

Now we must be clear that the final linear momentum must be equal to the original linear momentum plus the applied momentum. In this way we can deduce the following equation.

[tex](m_{1}*v_{1})+F*t=(m_{1}*v_{2})[/tex]

where:

m₁ = mass of the object = 10 [kg]

v₁ = velocity of the object before the impulse = 1 [m/s]

v₂ = velocity of the object after the impulse = 4 [m/s]

[tex](10*1)+F*5=10*4\\10+5*F=40\\5*F=40-10\\5*F=30\\F=6[N][/tex]

Answers

Answer:

V2 = 1.899*10^-3 m^3

Explanation:

Using gas law, we know that

PV = nRT,

Where

V1 = 0.00115743 m^3.

gamma = 1.4

Now, when we solve for final volume, V2 we get

V2 = V1/((P2/P1)^(1/gamma))

V2 = 1.899*10^-3 m^3

Using the same law and method, when we try to solve for the temperature, we find that the final temperature, T2 is

T2 = T1*((V1/V2)^(gamma-1))

T2 = 347.125 K

The final volume is 1.899*10^-3 m^3

And, the final temperature is 347.125 K

Gas law:

here we used gas law,

we know that

PV = nRT,

Here

V1 = 0.00115743 m^3.

gamma = 1.4

Now final volume is

V2 = V1/((P2/P1)^(1/gamma))

V2 = 1.899*10^-3 m^3

A ping pong ball of mass 0.0027 kg and radius 0.020 m is completely submerged 0.3 m in water. How fast is it moving when it emerges from the water?

Answers

Answer:

The value speed  is  [tex]v = 8.192 \ m/s[/tex]

Explanation:

From the question we are told that

   The mass of the ping pong ball is [tex]m = 0.0027 \ kg[/tex]

    The  radius is  [tex]r = 0.020 \ m[/tex]

     The depth of the ping pong inside the water is  [tex]s = 0.3 \ m[/tex]

Gnerally the force with which the ball will emerge will from the water is mathematically represented as

            [tex]F = B - m g[/tex]

Here B  is the Buoyant force on the ball which is mathematically represented as

         [tex]B = \rho_w * V_b * g[/tex]

Here  [tex]V_b[/tex] is the volume of the ball which is mathematically represented as

       [tex]V_b = \frac{4}{3} * \pi * r^3[/tex]

=>     [tex]V_b = \frac{4}{3} * 3.142 * 0.020 ^3[/tex]

=>     [tex]V_b = 3.35*10^{-5} \ m^3[/tex]

        [tex]\rho_w[/tex]  is the density of water with value  [tex]\rho_w = 1000 \ kg/m^3[/tex]

So  

       [tex]B = 1000 * 3.35*10^{-5} * 9.8[/tex]

=>    [tex]B = 0.3284 \ N[/tex]

So

     [tex]F = 0.3284 - 0.0027 * 9.8[/tex]

=>  [tex]F = 0.3284 - 0.02646[/tex]

=>  [tex]F = 0.3020 \ N[/tex]

Generally force is mathematically represented as

     [tex]F = m * a[/tex]

So

      [tex]0.3020 = 0.0027 * a[/tex]

=>  [tex]a = 111.84 \ m/s^2[/tex]

Generally  from kinematic equation

     [tex]v^2 = u^2 + 2as[/tex]

Here u  is the velocity of the ping pong at depth of  0.3 m and the value is zero given that at that point there was no motion

So

      [tex]v^2 = 0^2 + 2 * 111. 84 * 0.3[/tex]

=>    [tex]v = 8.192 \ m/s[/tex]

Answers

Answer:

The value is  [tex]v = 12.6 \ m/s[/tex]

Explanation:

From the question we are told that

    The horizontal force is  [tex]F_h = 350\ N[/tex]

    The mass of the ball is  [tex]m = 2.0 \ kg[/tex]

     The radius is     [tex]r = 0.90 \ m[/tex]

     

Generally the speed of the ball is mathematically evaluated from  the formula for  centripetal force as

         [tex]F_ h = \frac{mv^2}{ r }[/tex]

=>       [tex]v = \sqrt{\frac{ F_h * r }{ m }}[/tex]

=>       [tex]v = \sqrt{\frac{ 350 * 0.9 }{ 2 }}[/tex]

=>      [tex]v = 12.6 \ m/s[/tex]

Explanation:

Electric Current

The electric current is defined as a stream of charged particles that move through a conductive path.

The current intensity can be calculated as:

[tex]\displaystyle I=\frac{Q}{t}[/tex]

Where:

Q = Electric charge

t   = Time taken by the charge to move through the conductor

The current intensity is often measured in Amperes.

The charge passing through a point in a circuit is Q= 55 c during t=5 seconds, thus the current intensity is:
