Field strength is 0.03234 N/kg. The formula to determine the field strength is given by:

F = mg Here, F is the field strength, m is the mass, and g is the gravitational field strength.

Substituting the values given: Weight = 0.96 N Mass = 3.3 g = 0.0033 kg = 9.8 m/s² Therefore, F = mg = 0.0033 kg × 9.8 m/s² = 0.03234 N the field strength is the gravitational force acting on a unit mass. It is measured in newtons per kilogram. The field strength is an expression of the strength of a gravitational field. In this case, the mass of the object is 3.3 g, which can be converted to kilograms by dividing by 1000.

The weight of the object is given as 0.96 N. Using the formula

F=mg, where m is the mass and g is the gravitational field strength, we can calculate the field strength as 0.03234 N/kg.

Answer: The magnetic flux density at a distance of 20 cm from the moving charge is 2.5x10^-9 T

Explanation:

To calculate the magnetic flux density, we need to use the formula for the magnetic field created by a moving charge:

\(B=\frac{ u_{o} .q.v}{4\pi r^{2} }\)

where:

B is the magnetic flux density

\(u_{o}\) is the vacuum permeability constant

q is the charge of the moving charge (in coulombs)

v is the velocity of the moving charge (in m/s)

r is the distance from the moving charge (in meters)

In this problem, we have:

q = 3x10⁴ C (the rate at which the electric charge moves per minute)

v = ?

r = 0.2 m = 20 cm

To find the velocity (v), we need to convert the rate of electric charge to a current.

∴  \(I = \frac{q}{t}\)

where I is the electric current (in amperes) and t is the time (in seconds).

Since the rate is given in coulombs per minute, we need to convert the time to seconds:

t = 1 minute = 60 seconds

∴ I = q / t = (3x10^-4 C) / (60 s) = 5x10^-6 A

Now we can use the formula for the magnetic flux density:

\(B=\frac{ u_{o} .q.v}{4\pi r^{2} }\)

Putting the values, we get:

\(v = \frac{B.4\pi r^2}{u_{o}.q }\)

Simplifying, we get:

v = B * 2 * 10^3 m/s

Dividing both sides by 2*10^3 m/s, we get:

B = v / (2 * 10^3 m/s)

Plugging in the value of v, we get:

B = 5x10^-6 A / (2 * 10^3 m/s) = 2.5x10^-9 T

Therefore, the magnetic flux density at a distance of 20 cm from the moving charge is 2.5x10^-9 T.

If you are driving in Germany at 185 km/hr, your speed in miles per hour (mph) is approximately 114.953 mph.

To convert kilometers per hour (km/hr) to miles per hour (mph), we can use the conversion factor. The conversion factor for km/hr to mph is 0.621371. This means that for every kilometer traveled in one hour, the equivalent distance traveled in miles is approximately 0.621371 miles.

To convert km/hr to mph, we simply multiply the speed in km/hr by this conversion factor. Therefore, we have,

Answer:

9.92 m/s

Explanation:

We can use conservation of momentum to solve this problem. The total momentum of the system before the collision is:

p1 = m1 * v1 + m2 * v2,

where m1 and v1 are the mass and velocity of the clay ball before the collision, and m2 and v2 are the mass and velocity of the wooden block before the collision. Substituting the given values, we get:

p1 = 17 kg * 14 m/s + 7 kg * 0 m/s = 238 kg m/s.

After the collision, the clay and the block stick together and move as a single object with a combined mass of:

m = m1 + m2 = 17 kg + 7 kg = 24 kg.

Let the final velocity of the combined object be vf. Then, the conservation of momentum principle tells us that the total momentum of the system after the collision is:

p2 = m * vf.

Since momentum is conserved, we have p1 = p2, which gives us:

238 kg m/s = 24 kg * vf.

Solving for vf, we get:

vf = 238 kg m/s / 24 kg = 9.92 m/s.

Therefore, the clay and the block move together at a speed of 9.92 m/s after the collision.

The differential equation of motion for the system is given by the Lagrangian method when a particle of mass m is embedded at a distance r/4 from the center of a massless circular disc of radius r that can roll without slipping down a plane inclined at an angle a with the horizontal. Using the Lagrangian method, the differential equation of motion for

the system is given as follows:L = T - VL = [1/2 m(r² + (r/4)²)ω² + 1/2 Iω²] - mgrsin(α)r/4Here, I = [1/2 m(r/2)²] + m(r/4)²I = [1/2 m(r²/4 + r²/16)] + m(r²/16)I = m(r²/8)Therefore, I = mr²/4Then, the expression of Lagrangian can be given as:L = [1/2 m(r² + r²/16)ω² + 1/2 (mr²/4)ω²] - mgrsin(α)r/4L = [1/2 m(17r²/16)ω² + (1/8)mω²] - mgrsin(α)r/4L = [1/8 mω²(17r² + 2r²) - mgrsin(α)r/4]L = [1/8 mω²(19r²) - mgrsin(α)r/4]So, the Lagrangian equation of motion for the system is given as:D²θ/Dt² + (g/[(19/8) r]sin α)θ = 0

Answer:A 1000 kg car and a 2000 kg truck have the same momentum when the car is travelling at twice the speed of the truck, i.e. 38 m/s.

When a 1000kg car and a 2000kg truck have the same momentum, the speed of 1000 kg car is twice that of the  2000kg truck.

The product of a particle's mass and velocity is its momentum. Being a vector quantity, momentum possesses both magnitude and direction. According to Isaac Newton's second equation of motion, the force applied on a particle is equal to the time rate of change of momentum.

As  a 1000kg car and a 2000kg truck have the same momentum,

1000 kg × v₁ = 2000 kg × v₂

v₁ = 2v₂

Hence, the speed of 1000 kg car is twice that of the  2000kg truck.

At any given time, one-half of the Earth is illuminated by the sun (sunlight). The correct answer is option c).

This is because the Earth rotates on its axis once every 24 hours, causing different parts of the Earth to be exposed to sunlight at different times. As the Earth rotates, the half facing the sun experiences daytime, while the half facing away from the sun experiences nighttime.

The amount of sunlight that reaches the Earth's surface at any given location also depends on the tilt of the Earth's axis and its orbit around the sun. The Earth's axis is tilted at an angle of approximately 23.5 degrees relative to its orbit around the sun, which causes the seasons.

During the summer solstice, the hemisphere tilted towards the sun receives the most direct sunlight and experiences the longest day of the year, while the opposite hemisphere experiences the shortest day of the year.

During the winter solstice, the opposite occurs. During the equinoxes, the Earth's axis is neither tilted towards nor away from the sun, and both hemispheres experience equal amounts of daylight and darkness.

The system that is colliding maintains its momentum. As a result, the ball B's speed is 2m/s (option -a) when it has the same mass as the ball A.

A body's capacity to produce the greatest displacement from an applied force is known as momentum. It is the result of adding mass and speed. The two bodies' total initial momentum and total final momentum are equal in a collision.

Consequently, let u be the starting velocity and v be the ending velocity.

m₁ u₁+ m₂ u₂ = m₁ v₁ + m₁ v₂

m₁ =  0.17 kg

u₁ = 4 m/s

m₂ = 0.17 kg

u₂ = 0

Then initial momentum = 0.17 × 4 m/s + 0 = 0.68 kg m/s

v₁ = v₁ cos 30° = 3.5×√3/2

v₂ = v₂cos 60 = v/2

0.68 kg m/s = (0.17 × 3.5×√3/2 ) +  (0.17 × v₂/2)

3.5×√3/2/2 + v₂/2 = 4

3.5√3 + v₂ = 8

Answer:

\(v_y=53.9\ m/s\)

Explanation:

Horizontal Launch

When an object is thrown horizontally with a speed v from a height h, it describes a curved path ruled by gravity until it eventually hits the ground.

The horizontal component of the velocity is always constant because no acceleration acts in that direction, thus:

vx=v

The vertical component of the velocity changes in time because gravity makes the object fall at increasing speed given by:

\(v_y=g.t\)

The horizontal component of the velocity is always the same:

\(v_x=34 m/s\)

The vertical component at t=5.5 s is:

\(v_y=9.8*5.5=53.9\)

\(v_y=53.9\ m/s\)

To solve this problem, we can use the conservation of momentum principle which states that the total momentum before and after an event is always conserved.

Before the swimmer dives off the raft, the total momentum of the system (raft + swimmer) is:
Momentum before = Mass of raft x velocity of raft
Momentum before = 500 kg x 0 m/s (since the raft is stationary)
After the swimmer dives off the raft, the total momentum of the system (raft + swimmer) is:
Momentum after = (Mass of raft x velocity of raft) + (Mass of swimmer x velocity of swimmer)
Momentum after = 500 kg x v + 75 kg x 4 m/s
where v is the velocity of the raft after the swimmer dives off.
Since momentum is conserved, we can equate the two expressions:
Momentum before = Momentum after
500 kg x 0 m/s = 500 kg x v + 75 kg x 4 m/s
Solving for v, we get:
v = - (75 kg x 4 m/s) / 500 kg
v = -0.6 m/s
The negative sign indicates that the raft moves in the opposite direction of the swimmer's jump. Therefore, the raft speed after the swimmer dives off is 0.6 m/s in the opposite direction.
