Answer:

An air mass that is moving from the north pole toward the equator would be turned to the East because of the spinning of the earth on its axis

Explanation:

An air that is moving from the North pole toward the equator will be turned to the East (right) because of the spinning of the earth around its own axis.

The Coriolis Effect can be described as an apparent effect generated by a rotating frame of reference. The effect takes place when an object moving along a straight path can be viewed from a non-fixed frame of reference.

The moving frame of reference is the one in which the Earth rotates at a fixed speed.  The Coriolis effect creates wind patterns near the earth’s surface, that move to the east toward the equator and to the west toward the poles. These wind patterns are responsible for moving clouds around the globe and creating weather patterns.

Coriolis force can be described as a fictitious force resulting from the rotational movement of the earth. It only affects the wind direction and not the wind speed. The magnitude of Coriolis force can be calculated from the wind speed.

Answer: choices a and b

Explanation:

Telescope can be defined as am optical instrument which is designed to observe the distant objects clear and nearer. It comprises of arrangement of lenses which allow the rays of light to be collected. The collected light is focused and the image so produced is magnified in the form of an image. The telescopes are prepared and manufactured on mountains top as this will help in preventing the distortion of light obtain from the star due to the fluctuation of air mass in the atmosphere. The atmospheric distortion affects the resolution, and affects the vision. The atmospheric pressure is low at the mountain tops so it will help in better observation of the sky.

Answer:

Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy.

Explanation:

the velocity of sound in air is 330m/s

and v=fh, where h is wavelength f is frequency,

h=v/f.......(1)

longer wavelength

h=330/20,h=16.5m

shorter wavelength

h=330/20000,h=1.65x10-²m

The lesser frequency was used for finding the longer wavelength since wavelength is inversely proportional to frequency,

thus an increase in frequency brings a decrease in wavelength.

and shorter wavelengths are more high and intense

Answer:

d = 4.44 m

Explanation:

Given that,

The moment of force on a door = 10 N-m

The applied force, F = 2.25 N

We need to find the distance of the handle. The moment of force is given by :

[tex]\tau=F\times r[/tex]

Where

r is the distance of the handle.

[tex]r=\dfrac{\tau}{F}\\\\r=\dfrac{10}{2.25}\\\\r=4.44\ m[/tex]

So, the required distance is equal to 4.44 m.

Answer:

Let's take 20 as vf (final velocity) and 11 as (initial velocity) and 4 as time

So we would use this formula a=vf-vi/t

Answer:

The law of inertia is another name for Newton's first law. Newton's first law states that an object will not change its motion or direction unless a force acts on it. An object at rest will stay at rest and an object in motion will stay in motion if there isn't any force acting on them.

Example: When a car uses its brakes to stop, you sometimes feel like you are sliding forward. That is because the inertia keeps you moving forward, even though the car stopped.

Explanation:

Answer:

Law of inertia is sometimes called Newtons First law of motion.

Newtons first law of motion states that"A body will continue to its state of rest or motion unless external force acted upon it.

Answer:

According to our principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object has a negative acceleration. In Example D, the object is moving in the negative direction (i.e., has a negative velocity) and is speeding up.

Answer:

t = 6.63 s

Explanation:

Given that,

Initial velocity of the puck, u = 7.3 m/s

Deacceleration of the puck, a = -1.1 m/s²

Distance traveled, d = 5 m

We need to find the time the goalie have to stop the puck. Using equation of motion.

v = u +at

v = 0 (stops)

So,

[tex]u=-at\\\\t=\dfrac{u}{-a}\\\\t=\dfrac{7.3}{-(-1.1)}\\\\t=6.63\ s[/tex]

So, the required time is 6.63 seconds.

Complete Question:

A tungsten wire is 1.5 m long and has a diameter of 1.0 mm. A current of 60 mA flows through the wire. The resistivity of the wire is 5.6 * 10^-8 Ωm. What is the potential difference across the ends of the wire?

Answer:

Potential difference, V = 0.00642 Volts.

Explanation:

Given the following data;

Diameter = 1 mm to meters = 1/1000 = 0.001 m

Length = 1.5m

Current = 60mA = 60/1000 = 0.06 Amperes.

Resistivity = 5.6 * 10^-8 Ωm

To find the potential difference across the ends of the wire;

First of all, we would determine the cross-sectional area of the wire (circle);

[tex] Radius, r = \frac {diameter}{2} [/tex]

[tex] Radius = \frac {0.001}{2} [/tex]

Radius = 0.0005 m

Area of wire (circle) = πr²

Substituting into the above formula, we have;

Area  = 3.142 × (0.0005)²

Area = 3.142 × 2.5 × 10^-7

Area = 7.855 × 10^-7 m²

Next, we find the resistance of wire;

Mathematically, resistance is given by the formula;

[tex] Resistance = P \frac {L}{A} [/tex]

Where;

P is the resistivity of the material.

L is the length of the material.

A is the cross-sectional area of the material.

Substituting into the formula, we have;

[tex] Resistance = 5.6 * 10^{-8} \frac {1.5}{7.855 * 10^{-7}} [/tex]

[tex] Resistance = 5.6 * 10^{-8} * 1909611.712 [/tex]

Resistance = 0.107 Ohms.

Now, we can find the potential difference using the formula;

[tex] V = IR[/tex]

Where;

V represents voltage or potential difference measured in volts.

I represents current measured in amperes.

R represents resistance measured in ohms.

Substituting into the formula, we have;

[tex] V = 0.06*0.107[/tex]

Potential difference, V = 0.00642 Volts.

Answer:

Explanation:

The observer in the Northern Hemisphere will notice that the stars near the NCP to move counter-clockwise

Counter - clockwise : The observer will observe this because the earth movement when viewed from the North pole is in a counterclockwise direction, hence the stars will appear to move in an ant-clockwise direction
