What causes a partial lunar eclipse?
1. A partial eclipse causes the Moon to turn reddish from the refraction of the Sun's rays through the Earth atmosphere.
2. Only the penumbra of the Earth passes across the Moon, creating a circular shadow.
3. The Earth's umbra fits inside the Moon, creating an illuminated ring known as an annular eclipse.
4. The Earth's umbra only covers a part of the Moon causing a circular shadow to pass across it.

Answer:

In words, it could be said that the force times the time equals the mass times the change in velocity. In physics, the quantity Force • time is known as impulse. And since the quantity m•v is the momentum, the quantity m•Δv must be the change in momentum. The equation really says that the Impulse = Change in momentum.

Explanation:

Answer:

The displacement is 145 m in the north direction and the distance is 355 miles.

Explanation:

The distance traveled by a mobile is the length of its trajectory and it is a scalar quantity. In other words, distance refers to the space traveled by an object during its movement. It is calculated as the sum of all the distances traveled. In this case:

250 miles + 105 miles= 355 miles

On the other hand, displacement refers to the distance from a start position to an end position regardless of the travel. That is, like distance, displacement is a measure of length. Instead, the displacement is a vector quantity that depends on the direction, so it is described from the magnitude and the direction.

Mathematically, the displacement d is calculated as:

d = df - di

where df is the final position and di is the initial position of the object.

In this case:

displacement= 250 miles - 105 miles= 145 miles

Since the north distance is greater than the south distance, then the displacement is 145 m in the north direction and the distance is 355 miles.

Answer:

speed of object after 2 seconds will be 6 ms⁻¹

Explanation:

Initial velocity = 0

Final Velocity = 21 m/s

Time = 7 sec

We need to find speed of object after 2.0 seconds.

First we will find acceleration using formula: [tex]Accelaration=\frac{change \ in \ velocity}{change \ in \ time}[/tex]

Putting values:

[tex]Accelaration=\frac{Change \ in \ velocity}{Change \ in \ time}\\Accelaration=\frac{21-0}{7}\\Accelaration=\frac{21}{7}\\Accelaration= 3 \ ms^{-2}[/tex]

Now finding speed of object after 2 seconds

The formula used will be: [tex]Speed(v) = a\times t+v_0[/tex]

Putting values of a= 3m/s², t=2 sec and v₀=0 (at rest)

[tex]Speed(v) = a\times t+v_0\\Speed(v) = 3\times 2+0\\Speed(v) =6\ ms^{-1}[/tex]

So, speed of object after 2 seconds will be 6 ms⁻¹

Answer:

There are two reasons why air pressure decreases as altitude increases: density and depth of the atmosphere. Most gas molecules in the atmosphere are pulled close to Earth's surface by gravity, so gas particles are denser near the surface.

Let θ₁ and θ₂ denote the angles made by the tension forces T₁ and T₂ with the positive horizontal axis (directly to the right), respectively. (BTW, I write T₁ in boldface for the vector and T₁ for its magnitude.)

The ball is kept in equilibrium, so by Newton's second law both the net horizontal and net vertical forces are zero. This means

[1]   T₁ cos(θ₁) + T₂ cos(θ₂) = 0

[2]   T₁ sin(θ₁) + T₂ sin(θ₂) - m g = 0

Both cos(x) and sin(x) fall within -1 and 1 for any angle x, so right away we know that

T₁ sin(θ₁) + T₂ sin(θ₂) ≠ T₁ + T₂

so option (B) is not correct.

If T₁ = T₂, then in equation [1] we get

T₁ cos(θ₁) + T₁ cos(θ₂) = 0

T₁ (cos(θ₁) + cos(θ₂)) = 0

cos(θ₁) + cos(θ₂) = 0

which means θ₁ = 180° - θ₂, since cos(180° - x) = - cos(x) for any x. But this would require both strings to have the same length. So option (C) is also not correct.

The horizontal components of T₁ and T₂ are the only forces acting in the horizontal direction, so their horizontal components are equal. However, the vertical component of T₂ is closer to being parallel to the weight of the ball, which means T₂'s vertical component is almost enough on its own to counteract the ball's weight. This in turn means that (D)T₂ > T₁.

In other words, sin(θ₂) is closer to 1 than sin(θ₁), and T₂ is closer to m g than T₁.

Abstract

There are strong evidences linking physical outdoor activity and health benefits; however, little is known about the impact on environmental behaviors. Thus, this study aims to close this gap by investigating the influence of physical outdoor activity on environmental behaviors. A total of 416 surveys were distributed to students in eight public primary schools located near the Hsinchu Science and Industrial Park in Taiwan. Findings from the analysis revealed that subjective norms had a more influential effect on environmental behaviors for participants who engaged in physical activity at outdoor parks. In contrast, descriptive norms had a direct predictive impact on environmental behaviors for participants whose main physical activity venue was at the indoor after-school centers. Research results also highlighted attitude as the strongest predictive variable influence on environmental behaviors for children who engaged in physical indoor and outdoor activities

Answer:

1351.62 Watts.

Explanation:

The following data were obtained from the question:

Mass (m) = 79.5 kg

Height (h) = 2.29 m

Time (t) = 1.32 s

Acceleration due to gravity (g) = 9.8 m/s²

Power =?

Next, we shall determine the potential energy of the boy. This can be obtained as follow:

Potential energy (PE) = mass × acceleration × height

PE = m × g × h

Mass (m) = 79.5 kg

Height (h) = 2.29 m

Acceleration due to gravity (g) = 9.8 m/s²

Potential energy (PE) =?

PE = m × g × h

PE = 79.5 × 9.8 × 2.29

PE = 1784.139 J

Finally, we shall determine the power generated by Andrew as illustrated below:

Energy (E) = 1784.139 J

Time (t) = 1.32 s

Power (P) =?

P = E/t

P = 1784.139 /1.32

P = 1351.62 watts

Therefore, the power generated by Andrew was 1351.62 watts

Explanation:

The boat traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish. This statement is scientifically accurate description of velocity.

The rate at which a body's displacement changes in relation to time is known as its velocity. Velocity is a vector quantity with both magnitude and direction. SI unit of velocity is meter/second.

The boat traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes. In this statement both magnitude and direction is given. From this statement, the velocity of the boat is:

= 200/5 meter/minute in north direction.

= 40 meter/minute in north direction.

Explanation:

•Scientists have found that the rocks that make up the seabed are hidden in their "threads". This strip contains a record of the rotation of the Earth's magnetic field. The rocks on the seabed contain iron. ... When the rock cools down, the iron fragments inside align with the direction of the Earth's magnetic poles.

When the mass of the cannon increases and the energy of the blast remains the same, the total kinetic energy remains the same.

Kinetic energy refers to the form of energy that an object possesses due to its motion. It is known as the work that's required to move a body.

It should be noted that when there is an increase in the mass of the cannon while the energy of the blast remains the same, then in such a situation, the total kinetic energy will remain the same.
