Answer:

Written in Python

def energyvector(mass):

    c = 2.9979 * 10**8

    energy = mass * c ** 2

    print(round(energy,2))

Explanation:

This line defines the function

def energyvector(mass):

This line initializes the speed of light

    c = 2.9979 * 10**8

This line calculates the corresponding energy

    energy = mass * c ** 2

This line prints the calculated energy

    print(round(energy,2))

An exoplanet with one half of Earth's mass and 50% of Earth's radius is discovered.
Georgia [21]

Answer:

The space cadet that weighs 800 N on Earth will weigh 1,600 N on the exoplanet

Explanation:

The given parameters are;

The mass of the exoplanet = 1/2×The mass of the Earth, M = 1/2 × M

The radius of the exoplanet = 50% of the radius of the Earth = 1/2 × The Earth's radius, R = 50/100 × R = 1/2 × R

The weight of the cadet on Earth = 800 N

The \ weight, W  =G\dfrac{M \times m}{R^{2}} = 800 \ N

Therefore, for the weight of the cadet on the exoplanet, W₁, we have;

W_1   =G\dfrac{\dfrac{M}{2}  \times m}{ \left ( \dfrac{R}{2} \right ) ^{2}} = G\dfrac{\dfrac{M}{2}  \times m \times 4}{ R ^{2}} = 2 \times G \times  \dfrac{M \times m}{R^{2}} = 2 \times 800 \, N = 1,600 \, N

The weight of a space cadet on the exoplanet, that weighs 800 N on Earth = 1,600 N.

Can someone help me on how to do this?
Galina-37 [17]

Explanation:

Recall that

1\:\text{micron} = 1\:\mu\text{m} = 10^{-6}\:\text{m} so the speed of the bacterium is

v = \dfrac{6.82×10^{-6}\:\text{m}}{3.5\:\text{s}} = 1.9×10^{-6}\:\text{m/s}

Next, we convert this speed to km/hr. Recall that

1\:\text{km} = 1000\:\text{m}

1\:\text{hr} = 60\:\text{minutes} = 3600\:\text{s}

Therefore,

1.9×10^{-6}\:\dfrac{\text{m}}{\text{s}}×\left(\dfrac{1\:\text{km}}{1000\:\text{m}}\right)×\left(\dfrac{3600\:\text{s}}{1\:\text{hr}}\right)

= 6.8×10^{-6}\:\text{km/hr}
