The number of beats  the person have in 1.7 years is  6.7 x 10⁷ beats.

<h3>Number of beats of the person</h3>

The number of beats of the person is calculated as follows;

n = bt

where;

  • b is the beat rate
  • n is number of beats
  • t is time or duration

b = 75 beats/min

t = 1.7 years = 893520 mins

n = 75 beats/min x 893520 mins

n = 67,014,000

n = 6.7 x 10⁷ beats

Thus, the number of beats  the person have in 1.7 years is  6.7 x 10⁷ beats.

Regular treatment with low dose aspirin is used to help prevent cardiovascular disease. How many aspirin molecules are in
gogolik [260]

The number of molecules of aspirin is 4.01\times 10^{20} molecules

Given:

120. mg of the aspirin

To find:

The molecules of aspirin in 120. mg of aspirin.

Solution

Mass of aspirin = 120. mg

1mg = 0.001 g\\\\120. mg=120.\times 0.001 g=0.120 g

Molar mass of aspirin = 180.158 g/mol

Moles of aspirin == \frac{0.120 g}{180.158 g/mol}=0.000666 mol

According to the mole concept:

1 mole = N_A=6.022\times 10^{23} atoms/molecule/ions

The molecules of aspirin in 0.000666 moles of aspirin:

=0.000666\times 6.022\times 10^{23} molecules\\\\=4.01\times 10^{20} molecules

The number of molecules of aspirin is 4.01\times 10^{20} molecules.

1. Does the bowling ball have more potential energy or kinetic energy as it sit on top of the building? Why?
Luden [163]

The bowling ball have more gravitational potential energy as it sit on top of the building

<u>Explanation:</u>

The energy that is possessed by an object due to the position of that object in the field of gravity is called Gravitational potential energy . The object that is present in the place that is very closer to the Earth's surface has a constant gravitational potential energy. When an object is at certain height there is a necessity of force for lifting that object form that height.

This is applies to the  gravitational potential energy also.When two objects are placed at different heights, the object that is placed at the greater height will have more potential energy. This is because, the force necessary to take the object from greater height will be more.
