What makes carbohydrates good at storing energy?
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!

A lawyer most likely has __________. a.spatial intelligence b.practical intelligence c.analytical intelligence d.creative intelligence
The type of intelligence required by a profession depends on its job description. Lawyers most likes have analytical intelligence.
A renowned psychologist named Howard Gardner devised a theory of multiple intelligence. This means that nobody is really not intelligent because a person must posses one or more of these multiple intelligence.
A lawyer has a lot to do with analytic reasoning and comparison of evidence to determine their validity. This task requires a strong analytical mind hence a lawyer requires analytical intelligence.

a. How much chemical energy in Joules are in 15 gallons of gasoline?
b. The energy capacity of batteries, such as used in the Tesla cars, are given in kW hrs. Their standard battery is 7.0 kW hrs and the cost is a substantial fraction of the price of the car. What capacity would a battery have to be equal to the energy in 15 gallons of gas?
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.

a 15-kg block is on a frictionless ramp that is inclined at 20° above the horizontal. it is connected by a very light string over an ideal pulley at the top edge of the ramp to a hanging 19-kg block, as shown in the figure. the string pulls on the 15-kg block parallel to the surface of the ramp. find the magnitude of the acceleration of the 19-kg block after the system is gently released?
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].

Compared to permanent magnets, why are electromagnets more useful in
many modern technologies?
O A. In permanent magnets, the strength of the magnetic field is more
consistent.
O B. To use an electromagnet, a power supply is not necessary.
O C. Strong permanent magnets are too large to use.
O D. By controlling the current, electromagnets can be turned on and
off.
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"

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:
Jupiter's cloud formations and storm systems Volcanic activity on the Jupiter moon of IoInteresting discoveries about the rings of Saturn Voyager 2 discovered a huge magnetic field surrounding Uranus 10 additional moons seen to orbit Uranusand 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.

An object is moving 45 m/s and a mass of 34 kg , What is the kinetic energy?
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
