anzhelika [568]
The atomic number tells you the number of protons in an atom. This value never changes because the number of protons in the nucleus always remains constant. The mass number tells you the number of protons and neutrons (or nucleons) together: protons + neutrons = mass number. Since the number of neutrons in the nucleus varies, you can have different amounts of neutrons in the same type of atom. These varied types are called isotopes.

Hope this helps.

A particle of mass 2.37 kg is subject to a force that is always pointed towards East or West but whose magnitude changes sinusoi
Pavlova-9 [17]

Answer:

v(1.5)=0.7648\ m/s

Explanation:

<u>Dynamics</u>

When a particle of mass m is subject to a net force F, it moves at an acceleration given by

\displaystyle a=\frac{F}{m}

The particle has a mass of m=2.37 Kg and the force is horizontal with a variable magnitude given by

F=2cos1.1t

The variable acceleration is calculated by:

\displaystyle a=\frac{F}{m}=\frac{2cos1.1t}{2.37}

a=0.8439cos1.1t

The instant velocity is the integral of the acceleration:

\displaystyle v(t)=\int_{t_o}^{t_1}a.dt

\displaystyle v(t)=\int_{0}^{1.5}0.8439cos1.1t.dt

Integrating

\displaystyle v(1.5)=0.7672sin1.1t \left |_0^{1.5}

\displaystyle v(1.5)=0.7672(sin1.1\cdot 1.5-sin1.1\cdot 0)

\boxed{v(1.5)=0.7648\ m/s}
