Answer:
B. Electrons are transferred from the fur to the plastic rod.
Explanation:
Triboelectricity or friction charging refers to the ability of materials to gain or lose electrons as a result of rubbing them against something. This phenomenon has been observed in the case of rubbing plastic rod against fur, or glass rod against silk.
In the context of rubbing plastic rod against fur, what happens is that the fur which has an excess of charges loses electrons to the plastic rod. This makes the plastic rod to become positively charged, and the fur, negatively charged.
Answer:
Both vehicles experience the same change in momentum
Explanation:
Let m represent the mass of the vehicle, and 2m represent the mass of the large truck, and let v represent their initial speed, we have;
The total initial momentum, given as follows;
= 2·m·v - m·v = m·v
The total final momentum, = (2·m + m) ×
By the principle of conservation of linear momentum, the total initial momentum = The total final momentum
m·v = (2·m + m) ×
m·v = 3·m·
∴ v = 3 ×
= v/3
The change in the momentum for the large truck = 2·m·v - 2·m·
Therefore;
The change in the momentum for the large truck = 2·m·v - 2·m·v/3 = 2·m·(v - v/3)
The change in the momentum for the large truck = 2·m·(v - v/3) = 2·m·2·v/3 = 4·m·v/3
The change in the momentum for the car = m·v - m·(-) = m·v - m·(-v)/3 = m·v + m·(v)/3 = 4·m·v/3
Therefore, the change in the momentum for the large truck = The change in the momentum for the car and both vehicles experience the same change in momentum.
Answer:
planes, whereas the Oort cloud of comets has a spherical distribution.
Explanation:
A planet can be defined as a large celestial body having sufficient mass to allow for self-gravity and make it assume a nearly circular shape (hydrostatic equilibrium), revolves in an orbit around the Sun in the solar system and has a cleared neighborhood.
Basically, the planets are divided into two (2) main categories and these includes;
I. Outer planets: these planets are beyond the asteroid belt and comprises of jupiter, saturn, uranus and neptune, from left to right of the solar system.
II. Inner planets: these planets are the closest to the sun and comprises of mercury, venus, earth and mars.
These outer planets are made mostly of gases (hydrogen and helium) causing them to be less dense than the solid inner planets. These gases are generally known to be less dense in terms of physical properties.
Oort cloud is also referred to as Opik and it typically comprises of icy pieces of planetesimals (space debris) that spherically surrounds the sun at distances ranging from about 3000 to 100,000 AU.
Hence, the planets and the asteroid belt orbit the Sun in planes, whereas the Oort cloud of comets has a spherical distribution.
The object will stays the same.
Answer:Minerals are naturally occurring inorganic substances, often with a crystalline structure. They are composed largely of the most abundant elements in the Earth's crust, silicon and oxygen, coupled with metals or the metallic elements of iron, calcium, sodium, potassium, and magnesium.
