Protons

Explanation:

In a neutral atom, the number of electrons equals the number of protons in the atom.

Electrons are the negatively charge particles in an atom
Protons carry positive charge.
Neutrons do not carry any charges.

Protons and neutrons are contained in the nucleus of an atom they determine the mass number of the atom.

In a neutral atom, the number of protons and electrons must be the same.

A charge atom called an ion is one that has lost or gained electrons.

Slav-nsk [51]

Answer:

945 j

Explanation:

You have just given the ball kinetic energy, which is given by the following equation:

KE= 1⁄2 m v2 = 1⁄2 (2.1 kg)(30 m/s)2 = 945 Joules

An object of mass 30 kg is in free fall in a vacuum where there is no air resistance. Determine the acceleration of the object.

velikii [3]

Answer:

In free fall, mass is not relevant and there's no air resistance, so the acceleration the object is experimenting will be equal to the gravity exerted. If the object is falling on our planet, the value of gravity is approximately 9.81ms2 .

The mass of a spacecraft is about 435 kg . An engine designed to increase the speed of the spacecraft while in outer space provi

svlad2 [7]

Answer:

Δ v = 125 m/s

Explanation:

given,

mass of space craft = 435 Kg

thrust = 0.09 N

time = 1 week

= 7 x 24 x 60 x 60 s

change in speed of craft = ?

Assuming no external force is exerted on the space craft

now,

$T= m_s a$

$a=\dfrac{T}{m_s}$

$a =\dfrac{0.09}{435}$

a = 2.068 x 10⁻⁴ m/s²

using equation of motion

Δ v = a t

Δ v = 2.068 x 10⁻⁴ x 7 x 24 x 60 x 60

Δ v = 125 m/s
