Answer:

(a) 2.20 x 10^-4 N.

Explanation:

To solve this problem, you can use the formula for the gravitational force between two objects:

F = G * (m1 * m2) / r^2

where F is the gravitational force, G is the universal constant of gravitation, m1 and m2 are the masses of the two objects, and r is the distance between them.

Plugging in the given values, we get:

F = (6.67 x 10^-11) * (10,000 kg) * (10,000 kg) / (5.5 m)^2

= 2.20 x 10^-4 N

So the answer is (a) 2.20 x 10^-4 N.

Explanation:

The frequency heard by the person is 493.78Hz.

When the train moves toward the stationary observer then:

[tex]F=n(V/V-V_{s})[/tex]

Given:[tex]n=472,V=340m/s,V_{s}=15m/s[/tex]

[tex]F=472(340/340-15)\\F=493.78Hz[/tex]

What are the frequency and pitch of sound?

Sounds are higher or lower in pitch according to the frequency of vibration of the sound waves producing them. A high frequency (e.g., 880 hertz [Hz; cycles per second]) is perceived as a high pitch, and a low frequency (e.g., 55 Hz) as a low pitch.

How does the frequency of sound change with distance?

The frequency of sound doesn't decrease with distance, but it does decrease with increasing distance, meaning it does go through the doppler shift, the same as light. This is why the sound of a car driving by at high speeds drops in frequency as the car passes you.

Thus, the frequency at which the whistle is heard is 493.78Hz

Energy cannot be created or destroyed, according to the rule of conservation of energy. However, it is capable of change from one form to another. An isolated system's total energy is constant regardless of the types of energy present. The law of energy conservation is adhered to by all energy forms. The law of conservation of energy essentially says that

The total energy of the system is conserved in a closed system, also known as an isolated system.

Total energy of the chuck of ice at 553 m tall tower: E = mgh

If the average force due to air is W the, total energy of the ice at 353 m above the ground:

E = mgh + 1/2mv² + W(553-353)

=  25.0 × 9.8 × 353  + 1/2×25×30² + 200 W

= 97735 + 200 W joule

According to conservation of energy:

The system is working based on the Conservation of Momentum: A 5kg mass has a speed of 3m/s to the right when it hits and sticks to a 4 kg mass that moves with speed of 0.75m/s to the right (C). Both mass then move together with 2m/s to the right.

Conservation of momentum states that the total momentum of a system remains constant.

P = P'

Momentum is the product of a particle's mass and velocity. Momentum could be formulized as:

P = m.v

From the case, we know that:

m1 = 5kg

m2 = 4kg

v1 = 3m/s to the right

v1' = v2' = v' = 2m/s to the right

v2 = ?

Based on the conservation of momentum concept, we know that:

P = P'

where:

P = m.v

Hence:

P = P'

m1.v1 + m2.v2 = (m1 + m2)v'

5 (3) + 4 (v2) = (5+4) 2

15 + 4v2 = 18

4v2 = 3

This classification scheme, known as the Hubble sequence, is based on the observation that spiral galaxies can have different degrees of spiral arm tightness and different sizes of nuclear bulges. By comparing these two features, Hubble was able to divide spiral galaxies into three main categories: barred spirals, normal spirals, and flocculent spirals.

To solve this problem, we can use the following equations:

Linear speed: v = d/t

Angular speed: w = v/r

Spring compression: x = (1/2)kx^2

Conservation of energy: KE = PE

a) To find the linear speed of the center of mass after 3.82 m, we can use the equation v = d/t. We know that d = 3.82 m and t = 1 s (since the ball is starting from rest). Plugging these values into the equation gives us:

v = 3.82 m / 1 s = 3.82 m/s

This is the linear speed of the center of mass after 3.82 m.

b) To find the angular speed after 3.82 m, we can use the equation w = v/r. We know that v is 3.82 m/s (the linear speed we just found) and r is 0.27 m (the radius of the ball). Plugging these values into the equation gives us:

w = 3.82 m/s / 0.27 m = 14.15 rad/s

This is the angular speed of the ball after 3.82 m.

c) To find the spring compression, we can use the equation x = (1/2)kx^2. We know that k is 20 N/m (the spring constant) and x is the spring compression (which we are trying to find). Plugging these values into the equation gives us:

x = (1/2)(20 N/m)(x^2)

To solve for x, we can rearrange the equation to get:

x^2 = (2/k)x

Substituting in the value for k gives us:

x^2 = (2/20 N/m)x

Solving for x gives us:

x = sqrt(2/20 N/m) = 0.2 m

This is the spring compression.

d) To find the maximum linear speed, we can use the conservation of energy equation KE = PE. We know that KE is the kinetic energy of the ball (which is equal to (1/2)mv^2) and PE is the potential energy of the ball (which is equal to mgh, where m is the mass of the ball, g is the acceleration due to gravity, and h is the height of the incline). We also know that the ball starts at the top of the incline with a height of h = 10 m and that it rolls down the incline a distance of d = 3.82 m. We can use these values to find the final height of the ball, h2, using the equation h2 = h - d = 10 m - 3.82 m = 6.18 m.

Substituting these values into the conservation of energy equation gives us:

(1/2)mv^2 = mgh2

Solving for v gives us:

v = sqrt(2gh2/m) = sqrt(2(9.8 m/s^2)(6.18 m)/0.321 kg) = 6.58 m/s

This is the maximum linear speed of the ball.

e) To find the angular speed with the spring fully compressed, we can use the equation w = v/r. We know that v is the maximum linear speed we just found (6.58 m/s) and r is the radius of the

The speed of sound (velocity) is 343 m/s and a burglar alarm on a car has a frequency of 1200hz. 0.286 m/sec is the wavelength of the burglar alarm on the car.

Frequency is a unit of measurement for how frequently a recurrent event, like a wave, takes place over a specified period of time. A cycle is one repetition of the repeating pattern. Frequency only exists in moving waves that change their places throughout time. One method to describe how quickly a wave moves is by its frequency.

Therefore, if a wave passes through in half a second, the frequency is 2 per second. The frequency is 100 times per hour if it takes 1/100 of an hour.

Given that,

speed of sound (velocity) is 343 m/s

frequency of 1200 Hz.

Now as we know,

v = n × λ

The final temperature of the mixture is 17.9 °C.

The final temperature of the mixture can be found using the formula for heat exchange between two bodies at different temperatures: Q = mcΔT, where Q is the heat exchanged, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature.

For the tea, Q = mcΔT = (4.18 J/g·°C)(1.50 L)(1000 g/L)(75.0 - T)

For the ice, Q = mcΔT = (2.09 J/g·°C)(0.975 kg)(0 - T)

Since the total heat in the system is conserved, the heat gained by the tea is equal to the heat lost by the ice. So, we can set the two equations equal to each other and solve for T.

(4.18 J/g·°C)(1.50 L)(1000 g/L)(75.0 - T) = (2.09 J/g·°C)(0.975 kg)(0 - T)

T = (75.0 - (2.09 J/g·°C)(0.975 kg)/(4.18 J/g·°C)(1.50 L)(1000 g/L)) = 17.9 °C

So, the final temperature of the mixture is 17.9 °C.

The force that resists the motion of one solid object over another is known as friction. The four basic forms of friction are fluid friction, rolling friction, sliding friction, and static friction.

Friction is a sort of contact force. It exists between surfaces that are in touch with one another.

Given that,

The speed of the car to land safely on the opposite side will be 24.0 m/s. The speed of the car just before it lands on the other side will be 31.0 m/s.

(a) Speed is defined as the rate of change of the distance attained. it is a time-based quantity.

The equation for the position vector will be;

= r = x₀ + v₀xt,y₀ + v₀yt + (1/2)gt²

where,

r = the vector position of the car

vₓ = the initial horizontal velocity

vₐ = initial vertical velocity

t = time

y₀ =the initial vertical position

g =the acceleration due to gravity

v = the velocity at time t

From the figure, the origin of the frame of reference is located at y₀ = 0 and x₀ = 0.

The given position vector from the figure;

= r(final) = (48 -19.5) m

Then, employing the equations for the x and y-components of the vector r final, we will obtain;

= y = y₀ + v₀yt + (1/2)gt²

= y = (1/2)gt²

= -19.5 m = (1/2) X 9.8 X t²

= t = 2 s

By estimating the initial velocity at t = 2.00

The value is x-component of the vector r final is 48.0 m.

= x = x₀ + v₀xt   [x₀ = 0]

= 48 = v₀x X 2

= v₀x  = 24 m/s

Hence the speed of the car to land safely on the opposite side will be 24.0 m/s.

(b) The speed of the car just before it lands on the other side will be 31.0 m/s.

= v = (v₀x,v₀y + gt)

The y-component of v is given by;

= vₐ = v₀y + gt   [v₀y = 0]

=  vₐ = -9.8 X 2

=  vₐ = -19.6 m/s

The resultant speed  of the vector v will be :
