Answer:

4s

Explanation:

Using the formula of motion as follows:

V = u + at

Where;

V = final velocity (m/s)

U = initial velocity (m/s)

a = acceleration (m/s)

t = time (s)

Based on the provided information, v = 160m/s, u = 100m/s, a = 15m/s², t = ?

V = u + at

160 = 100 + 15t

160 - 100 = 15t

60 = 15t

t = 60/15

t = 4seconds.

Therefore, the time it takes for the plane to complete this increase in speed is 4s.

Answer:

The car's angular speed is [tex] \frac{rad}{s}[/tex].

Explanation:

Angular velocity is usually measured with [tex]\frac{radians}{sec}[/tex], so I'm going to use that to answer your question.

The relationship between tangential velocity and angular velocity (ω)  is given by:

[tex]V = \omega R[/tex]

Using the values from the question, we get:

[tex]2 \frac{m}{s} = \omega (0.4m)[/tex]

[tex]\omega = 5 \frac{rad}{s}[/tex]

Therefore, the car's angular speed is [tex]5 \frac{rad}{s}[/tex].

Explanation:

The question does not specify any outside forces that could slow down the ball horizontally. There fore the ball does not accelerate or decelerate horizontally. Therefore,  a = 0m/s2

Answer:

v₀ = 16.55 m/s

Explanation:

This motion of the ball can be modeled as a projectile motion with following data:

R = Range of Projectile = 27.5 m

θ = Launch Angle = 50°

g = acceleration due to gravity = 9.81 m/s²

v₀ = Initial Speed of Ball = ?

Therefore, using formula for range of projectile, we have:

[tex]R = \frac{v_{0}^2\ Sin2\theta}{g}\\\\v_{0}^2 = \frac{Rg}{Sin2\theta}\\\\v_{0}^2 = \frac{(27.5\ m)(9.81\ m/s^2)}{Sin100^o}\\\\v_{0} = \sqrt{273.93\ m^2/s^2}[/tex]

v₀ = 16.55 m/s

Answer:

The ratio is  [tex]k:d = 1 : 5[/tex]

Explanation:

From the question we are told that

   The first minimum of the single slit pattern falls on the fifth maximum of the double slit pattern.

Generally the condition for constructive interference for as single slit is  

     [tex]ksin(\theta) = n\lambda[/tex]

Here  k is the width of the slit  and n is the order of the fringe and for single slit n =  1 (cause we are considering the first maxima)

Generally the condition for constructive interference for as double slit is    

        [tex]dsin\theta = m\lambda[/tex]

Here  d is the separation between the  slit  and m is the order of the fringe and for double slit  m  =  5  (cause we are considering the first maxima)

=>     [tex]dsin\theta = 5\lambda[/tex]

So

       [tex]\frac{ksin(\theta)}{dsin(\theta)} = \frac{\lambda}{5\lambda}[/tex]

=>    [tex]\frac{k }{d} = \frac{1}{5}[/tex]

So  

      [tex]k:d = 1 : 5[/tex]

Answer:

W = 1526.43 J

Explanation:

Given that,

Force acting on a heavy crate, F = 325 N

The rope will make 29.0° angle with the horizontal

The distance covered by the crate, d = 5.37 m

We need to find the work done by the crate. The work done by an object is given by :

[tex]W=Fd\cos\theta\\\\=325 \times 5.37\times \cos29\\\\=1526.43\ J[/tex]

So, the required work done is 1526.43 J.

Answer:

The thickness of the tissue is : 2.4 x 10⁷ mm

Explanation:

The general formula for speed is the distance travelled divided by the time taken.

In this case,

Speed = 1600 m/s  ------speed of sound in human tissue

Time = 1.5 * 10 seconds -----time of taken for the ultrasound pulse to go through a certain thickness of a tissues

The thickness of the tissue here is the distance as per the speed formula, hence;

Tissue thickness = Speed of sound * time taken by ultrasound pulse

Tissue thickness= 1600 * 1.5*10 =24000 m

1 m= 1000 mm

24000m = 24000*1000 mm

= 2.4 x 10⁷ mm

Answer:

Explanation:

The work done by an object can be found by using the formula

workdone = force × distance

From the question we have

workdone = 50 × 8

We have the final answer as

Answer:

Velocity

Explanation:

The projectile has a height h at time t given by

h = (14.0 m/s) t - 1/2 g t ²

where g = 9.80 m/s² is the magnitude of the acceleration due to gravity. Solve for t when h = 0 :

0 = (14.0 m/s) t - 1/2 g t ²

0 = 1/2 t (28.0 m/s - g t )

1/2 t = 0   or   28.0 m/s - g t = 0

The first equation says t = 0, which refers to the moment the gun is first fired, so we ignore that solution. We're left with

28.0 m/s - g t = 0

t = (28.0 m/s) / g

t = (28.0 m/s) / (9.80 m/s²)

t ≈ 2.86 s

Answer:

the motion of the sled decrease

Explanation:

the mass increase

The acceleration of the sled will is inversely proportional to the mass on it. Therefore, the motion of the sled would slow if Joslyn's friend Lisa also wanted to ride.

Acceleration in mechanics can be described as the rate of change of velocity of an object with respect to time. The acceleration of an object is a vector quantities with magnitude and direction.

The S.I. unit for acceleration can be represented as m/s² the net balance of all external forces acting is equal to the magnitude of the net resulting force.

The force (F) acting on an object is equal to the product of the mass (m) of the object and acceleration (a) of an object.

F = ma

And, a = F/m

As shown in the above equation, the mass of the object is inversely proportional to the acceleration of the object, therefore, the acceleration of the sled decrease as the mass on it increases.

Answer :

556.59 m/s.

Explanation:

Given that,

An airplane is traveling at an altitude of 15,490 meters.

A  box of supplies is dropped from its cargo hold. We need to find the velocity of cargo when it hits the ground.

The initial velocity of the box is 0 as it as at rest. Let v is the velocity of cargo when it hits the ground. We can find it using third equation of motion as follows :

[tex]v^2-u^2=2as[/tex]

Put u = 0 and a = g

[tex]v^2=2gs\\\\v=\sqrt{2gs} \\\\v=\sqrt{2\times 10\times 15490 } \\\\v=556.59\ m/s[/tex]

So, when it hits the ground its velocity is 556.59 m/s.

Answer:

graph 1

Explanation:

When it comes to a graph showing "constant acceleration," the line should be straight and upward (positive acceleration) or straight and downward (negative acceleration). The variables for acceleration are time and velocity. The independent variable (time) should be placed on the x-axis while the dependent variable (velocity) should be placed on the y-axis. As time increases, the velocity increases the same way. It doesn't slow down or changes. This makes it constant. They are also directly proportional to each other. This is evident on the first graph.

The true statements about electric motion are:

An electrical device that transforms electrical energy into mechanical energy is an electric motor. The majority of electric motors work by creating force in the form of torque imparted to the motor shaft through the interplay of the magnetic field of the motor and electric current in a wire winding.

Electric generators function with a reversed power flow, transforming mechanical energy into electrical energy, and are mechanically identical to electric motors.

Electric motors can be powered by alternating current (AC) sources like a power grid, inverters, or electrical generators or by direct current (DC) sources like batteries or rectifiers.
