The voyager program was a space exploration program created to be the first to travel and explore the outer reaches of our solar system and beyond.

The voyager space probes were launched in 1977 and are still functional to this day, making them the longest running space exploration mission. The purpose of the voyager space probes is to relay information back to earth on the various planets and interplanetary objects they fly by.

Through these missions, NASA has received information regarding:

and much more, making it already an extremely successful mission.

The voyager spacecrafts were designed and built by the United States of America with government funding and contributions from other renowned space agencies.

As of 2021, voyager 1 is moving with a velocity of 61 thousand km per hour , with voyager 2 moving at roughly 55 thousand km per hour putting them beyond the outer reaches of the inner solar system. This along with the many important finds they are responsible for make them worth the 890 million dollars they cost to build.

To convert 15 gallons of gasoline to chemical energy in joule, multiply the figure above by 15 which is 1,800,000,000 Joules. Answer to b part is 60KWhrs

a.) A gallon of gasoline in most countries contain about 120 millions joule of chemical energy.

To convert 15 gallons of gasoline to chemical energy in joule, multiply the figure above by 15. That is,

Chemical energy = 15 x 120000000 = 1,800,000,000 Joules

b.) Also, the amount of energy cost per gallon of gasoline produced in most countries is equivalent to about 4 kilowatt hours. The capacity that would be equal to the energy in 15 gallons of  gasoline that a battery should have will be

Capacity = 4 x 15 = 60 KWhrs

Therefore, the capacity a battery will have to be equal to the energy in 15 gallons of gasoline will be 60 KWhrs.

We want to see why electromagnets are more useful in modern technologies.

We will see that the correct option is D:

"By controlling the current, electromagnets can be turned on and  off."

An electromagnet is, as the name implies, a magnet that works with a power supply.

Why these are more useful than normal magnets?

Because you have more control over them. By controlling the current, you not only can turn it on and off, but you also could regulate the strength of the magnetic field.

This extra control is what makes the electromagnet a better option than a permanent magnet.

So the correct option is D: "By controlling the current, electromagnets can be turned on and off"

Answer: KE = 34.425 kJ

Explanation:

KE = (1/2) mv^2

KE = (0.5)*(34kg)(45m/s)^2

KE = (0.5)*(34kg)(2025m^2/s^2)

KE = 34425 kg*m^2/s^2

1 Joule = 1 kg*m^2/s^2

KE = 34.425 kJ

Hi there!

Since the string is light and there is no friction in the pulley, the acceleration of the system is equal to the acceleration of both blocks.

We can begin by summing the forces of each block:

Block on incline:

- Force of gravity (in the negative direction away from the acceleration)

- Force of Tension

∑F = -M₁gsinФ + T

Block hanging:

- Force of gravity (Positive, in direction of acceleration)

- Force of Tension (Negative, opposite from acceleration)

∑F = M₂g - T

Sum both of these net forces for each block:

∑Fт = -M₁gsinФ + T - T + M₂g

∑Fт = -M₁gsinФ + M₂g

Divide by the mass to solve for acceleration:

[tex]a = \frac{-M_1gsin\theta+M_2g}{M_1+M_2}[/tex]

Plug in the given values:

[tex]a = \frac{-(15)(9.81)(sin20)+19(9.81)}{15+19} = 4.002 m/s^2[/tex]

The magnitude of the acceleration of the 19-kg block is 4.0 m/[tex]s^{2}[/tex].

The 15-kg block is accelerating down the ramp, and the 19-kg block is accelerating up. The string connecting the two blocks is taut, so it must be applying a force to both blocks. The force of the string on the 15-kg block is equal to the force of the string on the 19-kg block.

Let's call the force of the string on the 15-kg block T. We can use Newton's second law to write two equations for the acceleration of the two blocks:

For the 15-kg block: T - mg sin(θ) = 15a

For the 19-kg block: T = 19a

where:

m is the mass of the block

g is the acceleration due to gravity

θ is the angle of the ramp

a is the acceleration of the block

Plugging the second equation into the first equation, we get:

19a - mg sin(θ) = 15a

Solving for a, we get:

a = (mg sin(θ)) / (4m)

= (15 kg * 9.8  m/[tex]s^{2}[/tex] * sin(20°)) / (4 * 15 kg)

= 4.0 m/[tex]s^{2}[/tex]

Therefore, the magnitude of the acceleration of the 19-kg block is 4.0  m/[tex]s^{2}[/tex].

After we eat, our glucose levels rise when carbohydrates are fully broken down. This alarms beta cells (in the pancreas) to release insulin into our bloodstream and altogether insulin allows the glucose to enter our cells and be utilized for energy. Some carbs are used for energy and the rest is stored as fat!
