If the distance between the magnets tripled what would happen to the force between the 2 magnets?
Answer:
Our Repelling Force Magnet Calculator shows the repelling force on a magnet that happens when another magnet of the same size is placed at some distance from it, with like poles facing one another. The force depends on the distance between the magnets. The farther apart the magnets are, the weaker the force.
Explanation:
Consider three point charges, q1 = 4.50 C, q2 = 4.50 C, and q3 = 6.30 C, located at the corners of an isosceles triangle. The charges q1 and q2 are 5.00 m apart and form the base. The triangle is 3.50 m high, and q3 is located at the top. Calculate the magnitude and direction of the resultant force on q3.
Answer:
See explanation below
Explanation:
In this case, let's draw the triangle so we can see how the resultant force would be.
In the picture below, you have the drawn, and the procedure to solve this.

What is the difference between Mass and Weight?
Answer: Mass is the quantity of matter in an object whereas weight is the force of gravity on an object.
Weight is dependent on gravity while mass is independent on gravity

What is the importance of centre of curvature in spherical mirror?
Answer:
Rays of light parallel to the principal axis of a concave mirror will appear to converge on a point in front of the mirror somewhere between the mirror's pole and its center of curvature. That makes this a converging mirror and the point where the rays converge is called the focal point or focus .

A ball experiences forces of 14 N [N] and 9.2 N [W]. A Free Body diagram is required. What is the acceleration of the ball if its mass is 225 g?
Answer:
First, we can define the North as the positive y-axis, and the East as the positive x-axis.
Here we have two forces:
F₁ = 14N to north
F₂ = 9.2 N to west.
Then the free body diagram will be the one that can be seen below:
Now we want to find the acceleration that the ball experiences if the mass is 225g
Knowing that 1k = 1000g, we can rewrite the mass as:
M = 0.225g
Here we also need to remember the second Newton's law:
F = M*a
Net force equals mass times acceleration.
First, let's find the net force:
F = F₁ + F₂ = 14N*(0, 1) + 9.2N*(-1, 0 )
F = (-9.2N, 14N)
The module of the force is then:
I F I = √( (-9.2N)^2 + (14N)^2) = 16.75 N
Then the acceleration is given by
16.75 N = 0.225kg*a
(16.75 N)/(0.225 kg) = a = 74 m/s^2
A ball is released from a height of 20 metres. Calculate; 1. The time it takes to fall 2. The velocity with which it hits the ground
Answer:
Final velocity of ball = 20 m/s
Explanation:
Given:
Height when ball released = 20meter
Find;
Time taken to fall
Final velocity of ball
Computation:
Initial velocity of ball = 0 m/s
Acceleration due to gravity = 10 m/s²
Using equation of motion;
S = ut + (1/2)(g)(t²)
20 = (0)(t) + (1/2)(10)(t²)
20 = 5(t²)
(t²) = 20 / 5
(t²) = 4
Time taken to fall = 2 second
V = u + at
V = 0 + (10)(2)
Final velocity of ball = 20 m/s

. Calculate the equivalent resistance of the circuit.
c. Calculate the current through the battery.
d. How much current is passing through each resistor
[tex]\huge{ \mathfrak{ \underline{ Answer} \: \: ✓ }}[/tex]
1. Calculate the equivalent resistance in the circuit :
In the given diagram, the resistors are in series connection,
So equivalent resistance = sum of resistance of both resistors.
[tex] \large \boxed{R_{eq} =R_1 +R_2 }[/tex]
[tex]R_{eq} = 480 + 360[/tex][tex]R_{eq} = 840 \: ohms[/tex]Therefore, Equivalent resistance = 840 ohms.
2. Calculate the current through the battery :
[tex] \boxed{ \mathrm{current = \dfrac{potential \: \: difference}{resistance} }}[/tex]
[tex]i = \dfrac{120}{840} [/tex][tex]i = \dfrac{1}{7} [/tex][tex]i = 0.142 \: Amperes[/tex]Hence, current through the battery = 0.142 A
3. How much current is passing through each resistor :
Since the resistors are joined in series connection, the current flowing through each resistor will be equal = 0.142 Amperes.

The Hubble Space Telescope has a mass of 1.16*10^ 4 kg and orbits the Earth at an altitude of 5.68 * 10 ^ 5 above Earth's surface. Relative to infinitydetermine the potential energy the telescope at this location. Would the formula be Ep=-Gm1m2/r or positive G since it’s relative to infinity
Answer:
[tex]E=8.13\times 10^{12}\ J[/tex]
Explanation:
Given that,
The mass of a Hubble Space Telescope, [tex]m_1=1.16\times 10^4\ kg[/tex]
It orbits the Earth at an altitude of [tex]5.68\times 10^5\ m[/tex]
We need to find the potential energy the telescope at this location. The formula for potential energy is given by :
[tex]E=\dfrac{Gm_1m_e}{r}[/tex]
Where
[tex]m_e[/tex] is the mass of Earth
Put all the values,
[tex]E=\dfrac{6.67\times 10^{-11}\times 1.16\times 10^4\times 5.97\times 10^{24}}{5.68\times 10^5}\\\\E=8.13\times 10^{12}\ J[/tex]
So, the potential energy of the telescope is [tex]8.13\times 10^{12}\ J[/tex].

9. How is spring potential energy determined from a force versus position graph?
Answer: The potential energy associated with a mass attached to a spring depends on how much the spring is stretched or compressed. ... The gravitational force on the mass is −mg (“−” because the force points down). The force is the negative of the slope on the potential energy versus position graph.
Explanation:
:)
By getting the data from the graph of force versus displacement we can calculate the Potential energy of the spring.
What will be the potential energy?As we know that potential energy is defined as the energy possessed by the body due to its position with respect to other positions.
For an example the potential energy of an object if it is placed at height h will be due to the gravitational acceleration of the earth and is given by [tex]PE=mgh[/tex]
Similarly, for a spring-mass system, the potential energy will be due to the weight of the mass that will be the force exerted by the mass on the spring so there will be an extension in the spring.
So this extension will be found out by the force and displacement graph as the position of the mass attached to the spring goes down so the potential energy can be calculated as the
[tex]PE= F\times X[/tex]
[tex]F=mg[/tex] weight of the mass
X= deflection of the spring
Thus by getting the data from the graph of force versus displacement we can calculate the Potential energy of the spring.

the shock absorbers in a car act as a big spring with k= 21900 N/m. when a 92.5 kg person gets in, how far does the spring stretch?
Answer: 0.04139m
Explanation:
First, we need to calculate the weight of the man which will be:
Weight = mass × acceleration due to gravity
Weight = mg
Weight = 92.5 × 9.8
Weight = 906.5N
Then, we calculate the force which will be:
F = kx
mg = kx
x = mg/k
x = 906.5/21900
x = 0.04139m.
The spring stretched for 0.04139m.
Mr Mann cut a cucumber. Mr Mann said, you have performed a chemical change. Is he right?
Answer:
No.
Explanation:
The cut cucumber is still a cucumber.
Answer:
Nope.
Explanation:
Chemical change is transforming the cucumber into a pickle. However, you need vinegar, so it isn't a full change.
Therefore, Mr. Mann would not be right either way, because all he did was cut a cucumber, and he should probably get some help with all this "chemical change".

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

What would be the effect of an increase in greenhouse gas concentration in the atmosphere on Earth's average temperatures?
Answer:
See Explanation
Explanation:
Greenhouse gases are those gases that are believed to trap infrared rays close to the earth surface. Infrared radiation is otherwise known as heat rays due its heating effect.
Increase in the concentration of these greenhouse gases will ultimately lead to a gradual increase in the earth's average temperature. This phenomenon is referred to as global warming.
