A mother and daughter are playing catch, as seen in the image below. At which point
during the balls flight path does it have the most potential energy?
O When it leaves the mother's hand.
O When it leaves the little girls hand.
O The moment before either person catches the ball.
O The moment the ball is the highest in the air
Answer:
d the moment the ball is the highest in the air
Explanation:
for a, b, and c the ball is in movement which is kinetic energy. also the higher you are the more potential energy you will have.

What types of media can S-waves travel through
Answer:
The second type of body wave is the S wave or secondary wave, which is the second wave you feel in an earthquake. An S wave is slower than a P wave and can only move through solid rock, not through any liquid medium.
Which of the following is a property of an ionic compound?
A
has a low boiling point
B
forms molecules
C
is soft and flexible
D
conducts electricity when aqueous
Answer:
D
Explanation:
ionic compounds conduct electricity when molten or dissolved in water. ionic compounds conduct electricity when dissolved in water because water molecules are attracted to ions, this weakens the strong electrostatic forces of attraction between the oppositely charged ions. thus, ions are pulled away from the lattice structure and the remaining compound dissolves in water to form aqueous solution. The presence of free moving ions enables the ionic compound to conduct electricity.

According to Hooke's law, the force necessary to stretch or compress a spring is proportional to what value?
Answer:
displacement
Explanation:
Hookes Law describes the elastic properties of materials only in the range in which the force and displacement are proportional (displacement = change in length).
An upright object 2.80 cm tall is placed 16.0 cm away from the vertex of a concave mirror with a center of curvature of 24.0 cm. What is the focal length of this mirror?
Answer:
f = 12 cm
Explanation:
Center of Curvature:
The center of that hollow sphere, whose part is the spherical mirror, is known as the ‘Center of Curvature’ of mirror.
The Radius of Curvature:
The radius of that hollow sphere, whose part is the spherical mirror, is known as the ‘Radius of Curvature’ of mirror. It is the distance from pole to the center of curvature.
Focal Length:
The distance between principal focus and pole is called ‘Focal Length’. It is denoted by ‘F’.
The focal length of the spherical (concave) mirror is approximately equal to half of the radius of curvature:
[tex]f = \frac{R}{2}[/tex]
where,
f = focal length = ?
R = Radius of curvature = 24 cm
Therefore,
[tex]f = \frac{24\ cm}{2}[/tex]
f = 12 cm

Explanation:
Pulling a boat forward into a docking area requires 157J of work. The boat must be pulled a distance of 5.3m. What is the force with which the boat is pulled?
Answer:
29.62 N.
Explanation:
Work = 157 J
Distance = 5.3 m
Force = ?
Work = Force * Distance
157J = Force * 5.3 m
157 J/ 5.3 m = Force
29.62 N = Force (or) Force =29.62 N

A child easily pushes an empty shopping cart around the store. As the cart fills, the child has to exert more force to keep the shopping moving and keep up with his mom. Which law is best supported by this example?
A. Newton's First Law
B. Newton's Second Law
C. Newton's Third Law
D. The law of definite proportions
Answer:
B Newton's second law
Explanation:
An empty grocery cart is easier to move because there is less mass in an empty cart compared to a full cart. Newton's second law state that an object's acceleration depends on the mass of the object and the force applied.
A round asteroid has a surface gravity of .0288 m/s^2 if the mass of the asteroid is 1.10 x10^18 kg what is its radius
Answer:
r = 50.47 x 10³ m = 50.47 km
Explanation:
Using the formula for the acceleration due to gravity:
[tex]g = \frac{Gm}{r^2}[/tex]
where,
g = acceleration due to gravity on the surface of asteroid = 0.0288 m/s²
G = Universal Gravitational Constant = 6.67 x 10⁻¹¹ Nm²/kg²
m= mass of asteroid = 1.1 x 10¹⁸ kg
r = radius of asteroid = ?
Therefore,
[tex]0.0288\ m/s^2 = \frac{(6.67\ x\ 10^{-11}\ Nm^2/kg^2)(1.1\ x\ 10^{18}\ kg)}{r^2} \\\\r = \sqrt{\frac{(6.67\ x\ 10^{-11}\ Nm^2/kg^2)(1.1\ x\ 10^{18}\ kg)}{0.0288\ m/s^2}}[/tex]
r = 50.47 x 10³ m = 50.47 km
Answer:
5.05x10^4
Explanation:
g=(GM)/r^2, so
.0288=(6.67x10^-11*1.10x10^18)/r^2, r=5.05x10^4.
This is correct on Acellus.

Jasmine is investigating the effect force has on the motion of an object. She predicts if she puts a strong force on pushing a bowling ball, it will travel a farther distance than when a weak force is applied. Is her prediction correct? No, a weak or a strong force applied to the ball is unable to affect the motion of the ball. No, the force applied to the bowling ball should be a strong force. Yes, the force applied to the bowling ball affects the motion of the ball. Yes, the ball will travel a longer distance when a weak force is applied.
Answer:
I would like to attach options to the question above for clarity.
Jasmine is investigating the effect force has on the motion of an object. She predicts if she puts a strong force on pushing a bowling ball, it will travel a farther distance than when a weak force is applied. Is her prediction correct?
A. No, a weak or a strong force applied to the ball is unable to affect the motion of the ball.
B. No, the force applied to the bowling ball should be a strong force.
C. Yes, the force applied to the bowling ball affects the motion of the ball.
D. Yes, the ball will travel a longer distance when a weak force is applied.
The correct option is C (Yes, the force applied to the bowling ball affects the motion of the ball).
Explanation:
First, a force is any effort either push or pull that causes an object to undergo a change.
A bowling ball can remain at rest or in motion except a force acts on it. This brings us to the question above, the mass which affects force is not mentioned which means it is uniform or negligible. Recall that force = mass X acceleration. So the greater the force that is applied to the bowling ball the further distance it will travel. From the question, she applied a forward force (pushing), so the more force she applies the further the bowling ball will travel.
An empty water tank has a rectangular base with side lengths of 1.2 m and 2.3 m. The weight of the tank applies a pressure of 350 Pa to the surface it is resting on. What is the weight of the tank?
Answer:
Weight = 966 Newton.
Explanation:
Given the following data;
Length = 1.2 m
Width = 2.3 m
Pressure = 350 Pa
To find the weight of the tank;
We know that weight is the force of gravity acting on an object multiplied by its mass.
Weight = mg = force
Hence, we would determine the force using the parameters that were given.
But we would first determine the area of the rectangular tank.
Area of rectangle, A = length * width
A = 1.2 * 2.3
A = 2.76 m²
Mathematically, pressure is given by the formula;
Pressure = force/area
Force = pressure * area
Substituting into the formula, we have;
Force = 2.76 * 350
Force = 966 Newton
Therefore, the weight of the tank is 966 Newton.
