2. Viewed from somewhere in space above the Earth’s north pole, would a point on the Earth’s equator have a positive or negative angular velocity due to the Earth’s motion? Explain.

The potential of an infinite uniform line charge (lambda) is given by V(r) = lambda/(2πε*r), where ε is the permittivity of free space, and r is the distance from the line charge.

An infinite uniform line charge is a theoretical concept where a line of infinite length has a uniform charge density along its length. The potential of this line charge can be calculated using Coulomb's law, where the potential due to a point charge at a distance r is proportional to the charge and inversely proportional to the distance.

In this case, the line charge has an infinite length, so it can be considered as an infinite number of point charges. By summing up the potential due to each point charge, we can find the potential of the entire line charge. The result shows that the potential of an infinite uniform line charge is inversely proportional to the distance from the line charge, which satisfies the Laplacian equation.

The magnitude of the charge on each sphere is 7.22nC when two small metallic spheres each with a mass of 0.20 g pendulums equilibrium 30.0 cm.

Given the mass of each metallic sphere (m) = 0.20g = 20 x 10^-3kg

The length of the spring is (L) = 30cm = 30 x 10^-2m

The charge on two spheres is same = q

The angle of equilibrium = 5°

A force acting in the same direction as the string is called tension.

Let's denote the horizontal component as = Fx and

the vertical component as = Fy then the magnitude of tension is:

T = √Fx^2 + Fy^2

We can observe that the weight of gravity is the only other vertical force acting on mass. W = ma where a is acceleration due to gravity= -9.8m/s^2 Fy and W are equal because we are in equilibrium (mass is fixed and does not change position) (equal magnitude, opposite directions).

Fy = 20 x 10^-3 x 9.8 = 196 x 10^-3N

We can write utilizing the angle of the string as:

Fy = Tcos(5°)

Fx = Tsin(5°)

We know that electric force (Fe) = kq1q2/r^2 = 0.00197 * sin5

196 x 10^-3 * sin5 = 9 * 10^9 * q^2 / (0.3*(sin5)*2)^2)

q = 7.22nC

Hence, the charge on metallic sphere is 7.22nC

The atmospheric window is the atmospheric window of wavelengths of longwave radiation that escape to space is fairly narrow, at 8 to 15 microns.

The atmospheric window is the atmospheric window of wavelengths of longwave radiation that escape to space is fairly narrow, at 8 to 15 microns. This window is important because it allows the Earth to cool down by radiating excess heat into space. Longwave radiation is also known as terrestrial radiation or infrared radiation, and it is produced by the Earth's surface and the atmosphere.

The narrow range of wavelengths that make up the atmospheric window is critical because it allows the radiation to pass through the Earth's atmosphere with minimal absorption. If the atmospheric window were wider, more of the radiation would be absorbed by the atmosphere, and the Earth would not be able to effectively cool down.

The composition of the atmosphere and the amount of greenhouse gases it contains can impact the atmospheric window. For example, an increase in the concentration of greenhouse gases can trap more radiation in the atmosphere, reducing the size of the atmospheric window. This leads to an increase in the Earth's average temperature, which can result in global warming and climate change.

The acceleration is 0.10m/s2 when  a car originally traveling at 50.0 km/h in the positive direction accelerates at a rate of -0.400 m/s2 for 50.0 s.

Given the initial velocity of car (u)= 50km/h = 50 x 5/18 = 13.8m/s

The car accelerates at a rate = -0.400m/s2

The time taken to accelerate (t) = 50s

Let the final velocity = v

We know that from Newtons laws of Motion:

a = dv/dt = v - u/t

-0.400 x 50 = v - 13.8

v = 6.2m/s

The distance travelled = [tex]s = ut + 1/2at^2[/tex]

Then s = 13.8 x 50 - 1/2 x 0.4 x 50 x 50 = 190m

The final velocity of the car is 6.2m/s and as the acceleration remains constant during the travel which is equal to [tex]v^2 = 2as[/tex]

Velocity is a vector quantity that describes the rate of change of an object's position with respect to time. It is the magnitude of an object's displacement per unit of time, expressed as a speed in a specific direction.

Velocity is calculated by dividing the change in position (displacement) by the time interval in which the displacement occurs. It has units of distance per time (e.g. meters per second).

Require to find the velocity when t = 2 seconds

To find the velocity, find dy/dt

from the given

y = 40t - 16t^2

Now

y = 40t - 16t^2

dy/dt = d[40t − 16t^2]

dy/dt = 40(1) - 16(2t)

dy/dt = 40 - 32t

So, velocity is given by v(t) = 40 - 32t

Now let us find the velocity when t = 2 seconds
