Guys i need help please

Ball 1 has the greatest amount of potential energy inside it because it has the maximum height among all the balls shown in the graph.

Potential energy is the stored energy which depends upon the relative position of various parts of a system. A spring has more potential energy when it is compressed or stretched due to external force.

Potential energy is not affected by the environment outside of the object or its system, such as the air or height. On the other hand, kinetic energy is the energy of an object or a system's particles in motion.

The potential energy of an object depends on the force acting on the two objects. For the gravitational force, the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity and h is the height in meters.

The object 1 has maximum height hence, it has greatest potential energy.

Answer:

Electromagnetic waves.

Explanation:

Electromagnetic waves include microwaves, X-rays, gamma rays, and light waves, it carries energy and it can travel through matter or empty space.

Answer:

Electromagnetic waves or Light Waves

Explanation:

"Electromagnetic waves carry energy. The waves consist of transverse vibrations in electrical and magnetic fields, not vibrating particles. Electromagnetic waves do not need matter to travel through - they can travel through empty space (a vacuum)."

Answer:

Answer is: 162 g of beryllium.

Chemical reaction: Be + 2H₂O → Be(OH)₂ + H₂.

m(H₂) = 36,0 g.

m(Be) = ?

n(H₂) = m(H₂) ÷ M(H₂)

n(H₂) = 36,0 g ÷ 2 g/mol = 18 mol.

from reaction: n(Be) : n(H₂) = 1 : 1.

n(Be) = n(H₂) = 18 mol.

m(Be) = n(Be) · M(Be).

n(Be) = 18 mol · 9 g/mol = 162 g.

Answer:

Answer is: 162 g of beryllium.

Chemical reaction: Be + 2H₂O → Be(OH)₂ + H₂.

m(H₂) = 36,0 g.

Hey I'm working on this test right now, did you ever get the answers?

Answer:

a) N = 343 [N]

Explanation:

We must remember Newton's third law, which tells us that the force acting on a body is equal to the normal reaction force of equal magnitude but acting in the opposite direction.

[tex]N=m*g[/tex]

where:

m = mass = 35 [kg]

g = gravity acceleration = 9.81 [m/s²]

[tex]N = 35*9.8\\N= 343 [N][/tex]

Answer:

Transverse wave

Explanation:

It effects the balance of the plane, and slows it. Also you are likely moving faster than the bird, and it would be almost as if you are hitting a brick. However when it makes the plane impulse then it means the sudden loss of speed (even if it is a small bird) that is keeping the plane in the air causes the planes engines to struggle for a short amount of time, while it tries to recover the little amount of speed it has lost (the engines HAVE to regain full speed or the plane will turn to the ground, maybe not ALL the way but it still will lower the nose.

Answer:

a = - 5 [m/s²].

Explanation:

To solve this problem we must use Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration.

∑F = m*a

where:

F = resultant force [N] (units of Newtons)

m = mass = 50 [kg]

a = acceleration = 9.81 [m/s²]

For this particular problem, the only forces acting are the force of gravity acting down with negative sign, while the force of air opposes the fall, in this way it is positive.

[tex]f_{air}-F_{grav}=-m*a[/tex]

As the movement is pointing down the acceleration will be taken as negative.

[tex]740-(50*9.81)=-50*a\\740-490.5 = -50*a\\249.5 = -50*a\\a = - 5 [m/s^{2} ][/tex]

We should note that in this case, the acceleration has a negative sign, this means that the force of the air makes the skydiver move upwards

Answer:

The velocity of the boat and fisherman after he lands in the boat is 3.812m/s

Explanation:

We will solve this question on the general Derivation for general case of a man jumping n the boat

m = Mass of the man = 80kg

M= mass of the boat 37.5kg

V(m, g) = Velocity of man with respect to ground = 5.6m/s

V(b , g) = Velocity of boat with respect to ground = Vo = 0m/s ( rest)

velocity of the boat and fisherman after he lands in the boat = V1

As there is no external force acting on the man then we can apply conservation of the Linear Momentum.

m*V(m, g) + M*Vo = (M+m)V1

[tex]V1 = \frac{ m*V(m, g) + M*Vo}{M+m}[/tex]

 On substituting the values we get

V1 = [tex]\frac{80*5.6 + 37.5*0}{80+ 37.5}[/tex]

V1    = [tex]\frac{448}{117.5}[/tex] = 3.812 m/s

Therefore the velocity of the boat and fisherman after he lands in the boat is 3.812m/s.

Answer:

Explanation:

Answer:

333 m

Explanation:

The following data were obtained from the question:

Initial velocity (u) = 0 m/s.

Time (t) = 8.14 s.

Final velocity (v) = 80.79 m/s.

Acceleration due to gravity (g) = 9.8 m/s²

Height (h) =?

v² = u² + 2gh

80.79² = 0 + (2 × 9.8 × h)

6527.0241 = 0 + 19.6h

6527.0241 = 19.6h

Divide both side by 19.6

h = 6527.0241 / 19.6

h = 333 m

Thus, the plane was at a height of 333 m when the package was dropped.

Answer:

The ground pushes back on your feet with equal force

Explanation:

When you walk across the ground and push on it with your feet, the ground pushes back on your feet with an equal and opposite force.

This interpretation and knowledge is gotten from Newton's third law of motion.

It states that "action and reaction force are equal and opposite in nature".

Answer:

the answer is the second one: the ground pushes back on your feet with equal force
