Brianna fires a gun horizontally from a height of 500 m and with a muzzle velocity of 240 m/s. How fast does it travel horizontally after one second?

Answers

Answer 1
Answer: In this kind of projectile problem, we always ignore air resistance.  (At least
through high school Physics.)  If we tried to include air resistance, that would
make the problem hopelessly complicated, when all we're really trying to do is
work with the effects of gravity ... separating out what gravity does and what it doesn't do.

Ignoring the effects of air resistance, there is no horizontal force acting on
the bullet after it leaves the gun, so its horizontal acceleration is zero, and
its horizontal velocity doesn't change.  If it left the muzzle with a horizontal
velocity of 240m/s, then its horizontal velocity is that same number, from
then until it hits something.

(By the way . . . your question says that Brianna fires a gun horizontally, and
then it asks how fast does it travel after one second.  I took the liberty of
addressing the horizontal velocity of the bullet instead of the gun.)

You're taking your first dive in ALVIN (Fig 10.13) to witness a hot spot on the ocean floor. As you descend and arrive on site, what are your first impressions?

Answers

Answer:

Explanation:

The experience is magnanimous and wonderful when witnessing the hotspot site. It was a great feeling! I could witness the red hot lava oozing out to the ocean floor from the subsurface like water from a hot-spring, and immediately, a cooling effect occurs. At that current time, the gas was coming up in the form of gas bubbles. I believed there was a mini-volcano located inside the ocean! The scene was fascinating, just like inserting a red-hot metallic-iron ball into the cool water, thereby creating a fizzing of gas and the ball's immediate cooling. It was a remarkable experience of witnessing an underwater volcano with the erupting lava and its immediate cooling to form a solid material.

A mechanic turns a wrench using a force of 27.00 N at a distance of 16.00 cm from the rotation axis. The force is perpendicular to the wrench handle. What magnitude torque does she apply to the wrench?

Answers

Answer:4.32Nm

Explanation:

The magnitude of the torque will be the product of the force and its perpendicular distance from the force.

Force = 27N

Perpendicular distance = 16cm = 0.16m

Torque = 27×0.16

Torque = 4.32Nm

Discuss how lawmakers could use scientific knowledge to help them make decisions that would benefit society.

Answers

Scientific knowledge is very firm in its facts and pieces of evidence that create a more precise definition. If lawmakers are able to use the scientific method in making a decision, it will make a big change and will be beneficial to the society. The set of rules will be more arranged, specific and restrictive that might change justice, tax, and law.

what is the free-fall acceleration at the surface of the jupiter?you may have submitted the value posted in the internet. recall newton's law of universal gravitation and use the values for jupiter's mass and mean radius from the textbook.no credit lost. try again.

Answers

Answer:

The formula for acceleration due to gravity at the surface of a celestial body is:

a = (G * M) / r^2

Where:

G (the gravitational constant) is approximately 6.67430 x 10^-11 m^3 kg^-1 s^-2.

M (the mass of Jupiter) is approximately 1.898 x 10^27 kilograms.

r (the mean radius of Jupiter) is approximately 71,492,000 meters.

Now, let's calculate it:

a = (6.67430 x 10^-11 m^3 kg^-1 s^-2 * 1.898 x 10^27 kg) / (71,492,000 meters)^2

a ≈ 24.79 m/s^2

So, the free-fall acceleration at the surface of Jupiter is approximately 24.79 m/s^2.

Final answer:

The free-fall acceleration on the surface of Jupiter (g) is calculated by using Newton's Universal Law of Gravitation (g = G * M / r^2), where G is the gravitational constant, M is the mass of Jupiter and r is the radius of Jupiter.

Explanation:

To calculate the acceleration due to gravity at the surface of Jupiter, we can use Newton's Universal Law of Gravitation. It states that the force of gravity is equal to the gravitational constant (G) times the mass of the body (in this case, Jupiter) divided by the radius of the body squared. The formula can be expressed as F = G * (M * m / r^2), where F is the force of gravity, G is the gravitational constant, M is the mass of the larger body (Jupiter), m is the mass of the smaller body (object in question), and r is the distance between the centers of the two bodies - which is the radius of Jupiter when the object is on its surface.

The formula to find the acceleration due to gravity (g) on the surface of Jupiter is found by setting the weight of an object (F = m*g) equal to the gravity force (F = G * (M * m / r^2)) leading to the cancellation of the mass of the object (m). That results in g = G * M / r^2. This means that the acceleration due to gravity on the surface of Jupiter depends on the mass of Jupiter and the radius of Jupiter, and not on the mass of the object.

Explain how technology and science are related

Answers

When you're playing Angry Birds on your smart phone, you likely don't realize how important science is to what you're doing. As the birds catapult through the air, science is probably the last thing on your mind. Aside from the physics involved in sending feathered projectiles flying through the air, there's a far deeper connection between science and playing your favorite games. That's because all technology, from smart phones to medical scanners to cars, are intimately connected with science. Without science, they wouldn't exist.

Science is the study of the natural world by collecting data through a systematic process called the scientific method. And technology is where we apply science to create devices that can solve problems and do tasks. Technology is literally the application of science. So it really is impossible to separate the two. In this lesson, we're going to go into a little bit more detail about how science and technology are related, including some examples.
