A neutral atom of tin (Z = 50) has 69 neutrons. (a) How many protons does it have? (b) What is its mass number?

Olenka [21]

Answer:

Protons = 50

Mass number = 119

Explanation:

A neutral of tin, Sn, has a Z value of 50 and neutrons are 69.

Z is the atomic number. The atomic number is equal to number of protons or number of electrons in an atom that is neutral i.e:

Z = PROTONS = ELECTRONS

So the number of protons = 50 since Z is 50

>>>>>>>>>>>>>>>¦

The bulk of the mass of an atom is concentrated in the nucleus. To calculate mass number, we simply sum all the elementary particles in the nucleus i.e protons and neutrons. These particles are called the nucleons.

Mass number (A) = P + N

= 50 + 69

= 119

A tennis ball bounces on the floor three times. If each time it loses 11% of its energy due to heating, how high does it rise af

aalyn [17]

Answer:

h = 3.10 m

Explanation:

As we know that after each bounce it will lose its 11% of energy

So remaining energy after each bounce is 89%

so let say its initial energy is E

so after first bounce the energy is

$E_1 = 0.89 E$

after 2nd bounce the energy is

$E_2 = 0.89(0.89 E)$

After third bounce the energy is

$E_3 = (0.89)(0.89)(0.89)E$

here initial energy is given as

$E = mgH_o$

now let say final height is "h" so after third bounce the energy is given as

$E_3 = mgh$

now from above equation we have

$mgh = (0.89)(0.89)(0.89)(mgH)$

$h = 0.705H$

$h = 0.705(4.4 m)$

$h = 3.10 m$

What effect does an unbalanced force have on an object?

PSYCHO15rus [73]

Answer:

An unbalanced force can change an object's motion. An unbalanced force acting on a still object could make the object start moving. An unbalanced force acting on a moving object could make the object change direction, change speed, or stop moving.

A car is traveling down the highway cruise control at 50m/s (this means its is traveling with a constant velocity NOT accelerati

lawyer [7]

Given parameters:

Speed of car = 50m/s

Time of travel = 5minutes (300s)

Unknown;

Distance of travel = ?

To solve this problem, we need to understand how speed relates with distance and time.

Speed is a physical quantity. It is the distance traveled divided by time taken.

Speed = $\frac{distance}{time}$

So,

Distance = speed x time

Input the parameters and solve for the distance;

Distance = 50m/s x 300s

Distance = 15000m

The distance covered during this time interval and speed is 15000m
