I think it would be B because it is matter, since it has atoms, and it contains subatomic particles, which are smaller than atoms

Answer: Option (B) is the correct answer.

Explanation:

Anything that has space and occupies volume is known as matter.

A pure substance can be molecule of an element or molecule of a compound.

A molecule can have atoms of either same or different element. Whereas a compound has atoms of different elements.

For example, H_{2} is a molecule with similar atoms, that is, hydrogen element.

H_{2}O is a compound that contains hydrogen and oxygen atom.

Thus, we can conclude that pure substance contains molecule of an element or molecule of a compound.

Which nucleus completes the following equation?
IgorLugansk [536]

Answer: ^{50}_{25}Mn\rightarrow ^{0}_1e+ ^{50}_{24}Cr

The chromium nucleus will complete the reaction.

Explanation:

The given reaction is a type of radioactive nuclei decay:

Positron emission: It is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. This is also known as \beta ^+-decay. In this the mass number remains same.

_A^Z\textrm{X}\rightarrow _{Z-1}^A\textrm{Y}+_{+1}^0e

Now according to the given reaction:

^{50}_{25}Mn\rightarrow ^{0}_1e+ ^{50}_{24}Cr

The chromium nucleus will complete the reaction.

You are moving at a speed 2/3 c toward randy when randy shines a light toward you. at what speed do you see the light approachin
yarga [219]
I see the light moving exactly at speed equal to c.

In fact, the second postulate of special relativity states that:
"The speed of light in free space has the same value c<span> in all inertial frames of reference."
</span>
The problem says that I am moving at speed 2/3 c, so my motion is a uniform motion (constant speed). This means I am in an inertial frame of reference, so the speed of light in this frame must be equal to c.

A body A of mass 1.5kg, travelling along the positive x-axis with speed 4.5m/s, collides with another body B of mass 3.2kg which
Pie
Momentum before the collision
x-direction:
p = m₁v₁ = 1.5 * 4.5 = 6.75
x-direction:
p = 0

momentum after the collision is conserved:
x-direction:
p = 6.75 = m₁v₁ + m₂v₂ = 1.5 * 2. 1* cos -30° + 3.2 * v₂*cos θ
y-direction:
p = 0 = m₁v₁ + m₂v₂ = 1.5 * 2.1 * sin -30° + 3.2 * v₂ * sin θ

Solve the two equations for v₂ and θ.

A cyclist traveling at 5m/s uniformly accelerates up to 10 m/s in 2 seconds. Each tire of the bike has a 35 cm radius, and a sma
konstantin123 [22]

Answer:

a=2.5\ m/s^2

Explanation:

Given that,

Initial speed, u = 5 m/s

Final speed, v = 10 m/s

Time, t = 2 s

The radius of the tire of the bike, r = 35 cm

We need to find the angular acceleration of the pebble during those two seconds. It can be calculated as follows.

a=\dfrac{v-u}t{}\\\\a=\dfrac{10-5}{2}\\\\a=2.5\ m/s^2

So, the required angular acceleration of the pebble is equal to 2.5\ m/s^2.

If you don't wear a helmet and let's say you fell off your bike, you can severely injure your head! But if you DO wear a helmet and you fell off your bike, there's about I predict a 98% chance that you won't injure but sometimes it's 100%

hope this helps!<span />
