Answer: according to https://www.doe.virginia.gov When light strikes translucent materials, only some of the light passes through them. The light does not pass directly through the materials. ... Opaque objects block light from traveling through them. Most of the light is either reflected by the object or absorbed and converted to thermal energy.

Answer:

Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves. Most lightning occurs within the clouds. ... This heat causes surrounding air to rapidly expand and vibrate, which creates the pealing thunder we hear a short time after seeing a lightning flash.

Answer:

Lightning can be explained in terms of charges produced due to rubbing. During a thunderstorm, the air currents move upwards and the water droplets move downwards. And this caused due to the separation of charge due to this vigorous motion.

Answer:

223.25 [tex]$\text{Jm}^{-1}\text{s}^{-1}^\circ\text{C}^{-1}$[/tex]

Explanation:

The thermal conductivity of an object is defined as the measure or the ability of the object to transfer heat or conduct heat through its body.

In the context, the thermal conductivity of the material is given as

[tex]$=129 \text{ Btu ft}^{-1}\text{h}^{-1}^\circ\text{F}^{-1}$[/tex]

And it is given that :

1 Btu = 1055 J

1 ft = 0.3048 m

[tex]$1^\circ F = \frac{5}{9}^\circ C$[/tex]

We know that 1 h = 3600 s

So the thermal conductivity of the material in [tex]$\text{Jm}^{-1}\text{s}^{-1}^\circ\text{C}^{-1}$[/tex] is  :

Thermal conductivity :

[tex]$=\frac{129 \text{ Btu}}{1 \text{ ft }\times \text{1 h}\times 1^\circ\text{F}}$[/tex]

[tex]$=\frac{129 \times 1055 \text{ J}}{0.3048 \text{ m} \ \times 3600 \text{ s}\ \times \frac{5}{9}^\circ \text{C}}$[/tex]

=  223.25 [tex]$\text{Jm}^{-1}\text{s}^{-1}^\circ\text{C}^{-1}$[/tex]

Answer:

In a chemical reaction, an iron atom became the ion which means that iron atom by loosing two electrons from its valence shell has oxidized into positively charged ion

Explanation:

Answer:

Part A

Coriolis effect is used to describe how objects which are not fixed to the ground are deflected as they travel over long distances due to the rotation of the Earth relative to the 'linear' motion of the objects

Due to the Coriolis effect the wind flowing towards the Equator from high pressure belts in the subtropical regions in both the Northern and Southern Hemispheres are deflected towards the western direction because the Earth rotates on its axis towards the east

Part B

In the Northern Hemispheres, the winds are known as northeasterly trade winds and in the Southern Hemisphere, they are known as the southeasterly trade wind. Therefore, Coriolis effect has the same effect on the direction of the Trade Winds in the Southern Hemisphere as it does in the Northern Hemisphere

Answer:

A.  Car #1 has 2-times the momentum as Car #2

Explanation:

Momentum is defined as the product of mass and velocity:

[tex]P = mv[/tex]

where,

P = Momentum

m = mass

v = velocity

FOR CAR # 1:

m = 1000 kg

v = 10 m/s

Threfore,

[tex]P_1 = (1000\ kg)(10\ m/s)\\P_1 = 10000\ N.s[/tex]

FOR CAR # 2:

m = 500 kg

v = 10 m/s

Threfore,

[tex]P_2 = (500\ kg)(10\ m/s)\\P_2 = 5000\ N.s[/tex]

Dividing both momentums:

[tex]\frac{P_1}{P_2} = \frac{10000\ N.s}{5000\ N.s}\\\\P_1 = 2P_2[/tex]

Therefore, the correct option is:

A.  Car #1 has 2-times the momentum as Car #2

If a rocket of mass 117 kg is launched with a velocity of 800 m/s, so, the height is 32000m.

Kinetic energy is defined as the energy possessed by an object due to its motion that can be transferred between objects and converted into other forms of energy. It can be expressed as:

[tex]K.E.= 1/2 mv^2[/tex]

For above given information,

m is the mass which is 117kg

v is the velocity which is 8000m/s

So,

K.E.= [tex]1/2 (117)* (8000)^2[/tex]= [tex]3.744*10^7[/tex] Joules

So, we assume kinetic energy is equal to gravitational potential energy

G.P.E.= mgh

where, g is the gravitational strength which is 10N/kg for Earth

So,

[tex]3.744*10^7= (117).(10). h\\h= 3.744*10^7/1170\\h= 32000m[/tex]

So, the  rocket of mass 117 kg is launched with a velocity of 800 m/s, so, the height is 32000m.

Answer:

Space radiation is made up of three kinds of radiation: particles trapped in the Earth's magnetic field; particles shot into space during solar flares (solar particle events); and galactic cosmic rays, which are high-energy protons and heavy ions from outside our solar system.

Explanation:

Answer:

r = 0.0548 m

Explanation:

Given that,

Singly charged uranium-238 ions are accelerated through a potential difference of 2.20 kV and enter a uniform magnetic field of 1.90 T directed perpendicular to their velocities.

We need to find the radius of their circular path. The formula for the radius of path is given by :

[tex]r=\dfrac{1}{B}\sqrt{\dfrac{2mV}{q}}[/tex]

m is mass of Singly charged uranium-238 ion, [tex]m=3.95\times 10^{-25}\ kg[/tex]

q is charge

So,

[tex]r=\dfrac{1}{1.9}\times \sqrt{\dfrac{2\times 3.95\times 10^{-25}\times 2.2\times 10^3}{1.6\times 10^{-19}}}\\\\r=0.0548\ m[/tex]

So, the radius of their circular path is equal to 0.0548 m.

Answer:

V = 5.83 m/s

Explanation:

Given that,

Mass of a ball of a clay, m = 2 kg

Initial speed of the clay, u = 35 m/s

Mass of a box, m' = 10 kg

Initially, the box was at rest, u' = 0

We need to find the velocity of the box after the collision. Let V be the common speed. Using the conservation of momentum to find it.

[tex]mu+m'u'=(m+m')V\\\\V=\dfrac{mu+m'u'}{(m+m')}\\\\V=\dfrac{2\times 35+10\times 0}{2+10}\\\\V=5.83\ m/s[/tex]

So, the velocity of the box after the collision is equal to 5.83 m/s.

Answer:

Yes

Explanation:

An object can be moving (have kinetic energy) and be elevated above the ground at the same time (and also have potential energy).

Yes an object can be moving have kinetic energy and be elevated above the ground at the same time and also have potential energy.

Energy is the ability or capability to do tasks, such as the ability to move an item (of a certain mass) by exerting force. Energy can exist in many different forms, including electrical, mechanical, chemical, thermal, or nuclear, and it can change its form.

The energy an object has as a result of motion is known as kinetic energy. A force must be applied to an object in order to accelerate it. We must put in effort in order to apply a force. Following work, energy is transmitted to the item, which causes it to move at a new, constant speed. An object can store energy as the result of its position is potential energy.

An object can be moving have kinetic energy and be elevated above the ground at the same time and also have potential energy.
