Answer:

Average speed = 5 m/s

Explanation:

Given the following data;

Distance = 100m

Time = 20 secs

To find the average speed;

Speed = distance/time

Substituting into the formula, we have;

Speed = 100/20

Speed = 5m/s

Therefore, Elsa's average speed is 5 meters per seconds.

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:

An atomic nucleus contains most of the atom’s mass

Explanation:

The first and second answer choices are incorrect because the nucleus has a charge -- but it is positive due to the presence of protons.

The third answer choice is incorrect because the nucleus is extremely dense and packed with all of the protons and neutrons of the atom.

The fourth answer choice is correct because protons and neutrons contain the mass of the atom.

Answer:

His velocity at the bottom of his path is approximately 4.85 m/s

Explanation:

From the question, we have;

The mass of Frank, m = 30 kg

The length of the swing which he is sitting on, l = 2.3 m

The height above the lowest point to which the dad pulls him, h = 1.2 m

Potential energy, P.E. = m·g·h

Where;

g = The acceleration due to gravity ≈ 9.8 m/s²

The maximum potential energy Frank gains, P.E.[tex]_{max}[/tex] is goven as follows;

P.E.[tex]_{max}[/tex] = 30 kg × 9.81 m/s² × 1.2 m = 353.16 J

Therefore, by the principle of conservation of energy, we have;

The maximum kinetic energy at the bottom of the swing, K.E.[tex]_{max}[/tex] = P.E.[tex]_{max}[/tex] =  353.16 J

K.E. = 1/2·m·v²

Where;

v = The velocity at the bottom of his path

∴ K.E. = 1/2 × 30 kg × v² = 353.16 J

v² = 353.16 J/(1/2 × 30 kg)

v² = 23.544 m²/s²

v = √(23.544 m²/s²) ≈ 4.85 m/s

His velocity at the bottom of his path, v ≈ 4.85 m/s

Answer:

An incandescent bulb use electrical energy

Explanation:

Answer:

Time = 2758.62 seconds

Explanation:

Given the following data;

Speed = 290 m/s

Distance = 800 km to meters = 800 * 1000 = 800000

To find the time;

Time = distance/speed

Time = 800000/290

Time = 2758.62 seconds

Therefore, it will take the pilot 2758.62 seconds to reach the airport.

Answer:

a. The arrow follows a parabolic path

b. As the arrow hits the ground,

Explanation:

a Describe the arrow's trajectory, in particular noting approximately when the arrow has the most deceleration, the most acceleration, and then why the shift begins to happen. Cover all major points in the trajectory from initial shot to final resting place.

This is because, the arrow is a projectile and its path follows a parabolic curve as it goes from initial shot to final resting place.

Its equation of motion is governed by y = ut - 1/2gt² where y = parabolic path, u = initial speed of arrow, t = time and g = acceleration due to gravity.

As the arrow rises, it undergoes the most deceleration. This is because as it rises, its speed decreases until it gets to the peak of its path, where its velocity is momentarily zero.  

Also, as the arrow drops, it undergoes the most acceleration. This is because as it drops from its peak, its speed increases until it gets to the bottom of its path, where its velocity is maximum and given by v = u' - gt where u' = velocity at peak = 0 m/s. So, v = 0 - gt = -gt.

b. When is the arrow moving fastest?

As the arrow hits the ground, its velocity is highest (maximum), so it is fastest at this point.

Answer:

Bananas are curved because they grow towards the sun

Explanation:

Bananas are curved so they can retrieve sunlight. Bananas go through a process called 'negative geotropism'. What it means is that bananas grow away from the ground, instead of growing towards it, hence the 'negative' geotropism.

Answer:

Because they grow towards the sun and the sun is what makes things grow like water to  Beneath each flower petal, a row of tiny banana fruits start to grow. Once they're much bigger in size, the fruit goes through a process called negative geotropism. Which basically means instead of continuously grow towards the ground, they start to turn towards the sun, in order to retrieve light.

Answer:

7.5 N/m

Explanation:

Potential energy of a spring can be calculated using below formula

Potential energy= 1/2kx^2

potential energy = 60 J

X= displacement = 4 m

K= spring constant=?

Substitute the values we have

60= 1/2 × K × 4^2

60= 1/2 × K × 16

60= K × 8

K= 7.5 N/m

Hence, the spring constant of the spring is 7.5 N/m

Answer:

The coin will reach a vertical height of 0.027 meters before it stops rolling.

Explanation:

Let suppose that coin-ground system is a conservative system and begins at a height of zero. Since the coin is experimenting a general plane motion, which is a combination of translation and rotation. By Principle of Energy Conservation we have the following model:

[tex]K_{T}+K_{R} = U_{g}[/tex] (1)

Where:

[tex]K_{T}[/tex] - Translational kinetic energy at the bottom of the incline, in joules.

[tex]K_{R}[/tex] - Rotational kinetic energy at the bottom of the incline, in joules.

[tex]U_{g}[/tex] - Gravitational potential energy at the top of the incline, in joules.

By definitions of Kinetic and Gravitational Potential Energy we expand (1):

[tex]\frac{1}{2}\cdot I \cdot \omega ^{2} + \frac{1}{2}\cdot m\cdot R^{2}\cdot \omega^{2} = m\cdot g\cdot h[/tex] (2)

Where:

[tex]I[/tex] - Momentum of inertia of the coin, in kilogram-square meters.

[tex]\omega[/tex] - Angular speed, in radians per second.

[tex]R[/tex] - Radius of the coin, in meters.

[tex]m[/tex] - Mass, in kilograms.

[tex]g[/tex] - Gravitational acceleration, in meters per square second.

[tex]h[/tex] - Height reached by the coin, in meters.

The momentum of inertia of the coin is calculated by:

[tex]I = \frac{1}{2}\cdot m\cdot r^{2}[/tex] (3)

Then, we expand and simplify (2):

[tex]\frac{3}{4}\cdot R^{2}\cdot \omega^{2} = g\cdot h[/tex]

[tex]h = \frac{3\cdot R^{2}\cdot \omega^{2}}{4\cdot g}[/tex]

If we know that [tex]R = 0.0108\,m[/tex], [tex]\omega = 55.2\,\frac{rad}{s}[/tex] and [tex]g = 9.807\,\frac{m}{s^{2}}[/tex], then the height reached by the coin is:

[tex]h = 0.027\,m[/tex]

The coin will reach a vertical height of 0.027 meters before it stops rolling.
