Answer:

The magnitude of acceleration of the student is 0.6 m/s²

Explanation:

Given that,

Initial velocity = 2.8 m/s

Final velocity = 4.7 m/s

Time = 3.4 sec

We need to calculate the magnitude of acceleration of the student

Using formula of acceleration

\(a=\dfrac{v_{f}-v_{i}}{t}\)

Where, \(v_{f}\) = final velocity

\(v_{f}\) = final velocity

t = time

Put the value into the formula

\(a=\dfrac{4.7-2.8}{3.4}\)

\(a=0.6\ m/s^2\)

Hence, The magnitude of acceleration of the student is 0.6 m/s²

(a) It can be stated that the 10-gram marble hits the ground first because it has a higher acceleration and travels faster.

(b) Both marbles will travel the same distance since their horizontal components of velocity and initial velocity with respect to the ground are the same.

According to the given statement, a 10-gram marble has a speed that is 5 times faster than that of a 100-gram marble. Both marbles roll off the table at the same time. The questions to answer are as follows:

(a) The acceleration due to gravity is constant at 9.8 m/s², according to Newton's Law of Gravitation.

According to the law of physics, heavier objects fall faster than lighter ones, but since the 10-gram marble has a speed that is five times faster than the 100-gram marble, it implies that the 10-gram marble covers more ground in less time than the 100-gram marble as acceleration is directly proportional to the force applied.

The time taken by both marbles to reach the ground is given byt = √(2h/g)where h is the height from which the marbles were dropped, and g is the acceleration due to gravity.

The height from which the marbles were dropped is the same in both cases, so it can be stated that the 10-gram marble hits the ground first because it has a higher acceleration and travels faster.

(b) The range traveled by both marbles is determined by the horizontal component of their velocity. It's worth noting that the horizontal components of their velocities are identical since they were launched from the same height, so there's no advantage for either marble.

The range of a projectile is determined by the formula:

R = u²sin(2θ)/g where R is the range, u is the velocity of the object, θ is the angle of the initial velocity with the horizontal, and g is the acceleration due to gravity.

Since the angle of the initial velocity with the horizontal is the same for both marbles, and their initial velocity is also the same, it can be stated that both marbles travel the same distance.

Therefore, both marbles will travel the same distance since their horizontal components of velocity and initial velocity with respect to the ground are the same.

Explanation:

In the specific example of butane, a Gauche conformation, an angle larger than 60 helps spread the methyl groups further apart from one another (the C₂ and C₃ carbon atoms in particular).

Fully gauche-staggered and partially gauche-staggered conformations of n-butane have dihedral angles between two methyl groups of 60 and 300, respectively.

The two methyl groups in butane form the gauche conformation when their dihedral angles are 60° and 300°. This occurs because the methyl groups are still very close to one another (approximately 3.1, as opposed to 2.9 for the syn- conformation). Around 0.9 kcal/mol is the strain energy of the gauche contact.

The initial velocity of the ball thrown from the top of a building is 13.29 m/s.

When an object is thrown at an angle from the horizontal direction, the object is said to be in projectile motion. The object which follows the projectile motion is called projectile.

A ball thrown horizontally from the top of a building 24 m above the ground strikes the ground at the distance of 18 m from the base of the building.

Range of a projectile is given by

R = u²sin2θ /g

where θ =0°, g =9.81 m/s²

Put the values, we get

18 =  u² /9.81

u = 13.29 m/s

Thus, the initial velocity is 13.29 m/s.

Most of our solar system's large moons orbit their planets in the same direction as their planet rotates.

There is a long answer to this question because it depends on what is considered a "large" moon and which planets are being considered. However, in general, most of the large moons in our solar system do orbit their planets in the same direction as their planet rotates. For example, Earth's moon orbits in the same direction that Earth rotates. Similarly, Jupiter's largest moons (such as Io, Europa, and Ganymede) also orbit in the same direction as Jupiter's rotation.

However, there are some exceptions. For example, Neptune's largest moon, Triton, orbits in the opposite direction of Neptune's rotation. Overall, it can be said that about two-thirds of the large moons in our solar system orbit their planets in the same direction as their planet rotates, while about one-third orbit in the opposite direction.

Hi there!

\(\large\boxed{\text{B) 20 meters}}\)

We know that:

\(E_T = U + K\)

U = Potential Energy (J)

K = Kinetic Energy (J)

E = Total Energy (J)

At 10m, the total amount of energy is equivalent to:

U + K = 50 + 50 = 100 J

To find the highest point the object can travel, K = 0 J and U is at a maximum of 100 J, so:

100J = mgh

We know at 10m U = 50J, so we can solve for mass. Let g = 10 m/s².

50J = 10(10)m

m = 1/2 kg

Now, solve for height given that E = 100 J:

100J = 1/2(10)h

The maximum distance the spring compresses is A) 0.25 cm or 2.5 × 10^-3 m.

The initial kinetic energy of the object is converted into elastic potential energy stored in the spring when it comes in contact with the spring. At the maximum compression, all the kinetic energy is converted into elastic potential energy.

The maximum compression of the spring is given by the equation ∆x = (mv^2)/(2k), where m is the mass of the object, v is its initial velocity, and k is the spring constant.

Plugging in the given values, we get ∆x = (4.0 kg × (5.0 m/s)^2)/(2 × 40,000 N/m) = 2.5 × 10^-3 m = 0.25 cm. Therefore, the maximum distance the spring compresses is 0.25 cm or 2.5 × 10^-3 m. The correct answer is (A).

The acceleration of a circular track if a car's speedometer reads 32 m/s and the track has a radius of 56 m is 18.29 m / s²

\(a_{c}\) = v² / r

\(a_{c}\) = Centripetal acceleration

v = Linear / Tangential velocity

r = Radius

v = 32 m / s

r = 56 m

\(a_{c}\) = 32² / 56

\(a_{c}\) = 1024 / 56

\(a_{c}\) = 18.29 m / s²

Centripetal acceleration is the acceleration of an object in circular motion. It is always acting to center point with which the object is rotating about. The velocity used in the formula is tangential velocity which acts perpendicular to the motion of the object.

Therefore, the acceleration of a circular track is 18.29 m / s²

Explanation:

Given that three sharks are located at the vertices of an equilateral triangle whose side equals LL. They all start moving simultaneously with a constant speed vv, with the first shark heading constantly toward the second, the second toward the third, and the third toward the first. How soon will the sharks converge at one point ?

Since the three sharks are located at the vertices of an equilateral triangle whose side equals, and the first shark is moving toward the second, the second is moving toward the third, and the third shark is moving toward the first, the movement of the three shark will form a circular motion.

Since the three sharks are moving at a constant speed, the three sharks will never meet because the distances between them are also the same.

The three sharks will therefore continue to move till infinity.

Two astronomical teams that were both observing type I supernovae in 1998 provided crucial evidence for cosmic acceleration.

Any class of violently exploding stars whose luminosity after eruption abruptly reaches many millions of times its normal level is referred to as a supernova, plural supernovae, or supernovas. The word nova, which means "new" in Latin and refers to one sort of exploding star, is where the word supernova originates. In numerous ways, supernovae and novae are similar. Both exhibit a strong, quick brightening that lasts for a few weeks, followed by a gradual dimming.

Cosmic rays are also released during supernovae explosions, along with vast quantities of radio waves and X-rays. Gamma-ray bursts and supernovae have occasionally been linked.
