Actually Welcome to the concept of distance formula.
Distance formula ==>
\( \sqrt{( {x2 - x1})^{2} + ( {y2 - y1})^{2} } \)
so applying this we get as,
D = underoot (9)^2 + (-5)^2
==> D = 10.29 units
distance = 10.29 units

metals. One rod is a magnet; one is made of copper; and one is
made of iron. She does not know which rod is which. Each rod
has a dot at one end. (a)Hannah uses only a bar magnet to identify
each rod. She puts each pole of the bar magnet next to the
dotted end of each rod. Complete Hannah's observations in the
table below. Write if each rod is copper, iron or a magnet.
Answers
The iron rod gets magnetized when placed near a bar magnet due to magnetic induction while the copper rod does not get magnetized.
What is magnetic induction?
Magnetic induction is the process through which a regular piece of iron briefly develops magnetic properties as a result of another magnet being nearby.Consider a tong nail. Place it on a stand's arm. Spread some iron pins throughout the stand's foundation. You'll discover that the pins are not drawn to the nail. Touch a magnet to the nail's tip now. Some pins stick to the nail as the end is brought close to the head. It occurs as a result of the nail transforming into a magnet and acquiring magnetic properties. when the magnet is taken out of the nail's head the pins are about to drop.To know more about magnetic induction, click the link given below:

Remember, for energy to be transformed, the type of energy before and after a task must be different. (10 points) As you look around you, make note of technology that is turned on and off. This indicates that some sort of energy is present before the switch is flipped. Also look at objects that move from one height to another, because that will involve kinetic and gravitational potential energy.

Which of the following diagrams shows the greatest magnitude net torque with a zero net force? All the rods, of length 2r, rotate about an axis that is perpendicular to the rod and fixed in the center of the rod. All the forces are of magnitude F or 2F and all distances from the axis are r or r/2.
Answers
The diagram that shows the greatest magnitude net torque with a zero net force is the diagram in second option.
option B is the correct answer.
What is net torque?
The net torque is the sum of the individual torques. The torque itself is obtained from the product of applied force and the perpendicular distance of the force.
In rotational equilibrium, there is no net torque on the object. There may be individual torques, but they add up to zero and cancel each other out.
Mathematically, the formula for torque is given as;
τ = Fr
where;
F is the applied forcer is the perpendicular distanceThe torque applied to an object increases with increase in the perpendicular distance.
To obtain a zero net force, sum of all the opposite forces applied to an object must be equal to zero.
The forces must be equal in magnitude but opposite in direction, and the diagram that meets this specification is the last graph.

Answers
The amount of charge that will pass through the cross-sectional area of the conductor in 1 min is 192 C.
What is the amount of charge?
We can use the formula Q = I * t,
where;
Q is the amount of charge, I is the current, and t is the time.Given that a charge of 6.4 C passes through a cross-sectional area of the conductor in 2 s, we can find the current using the formula:
I = Q / t = 6.4 C / 2 s = 3.2 A
So, the current through the conductor is 3.2 A.
To find the amount of charge that will pass through the cross-sectional area of the conductor in 1 min (60 s), we can use the same formula:
Q = I * t = 3.2 A * 60 s = 192 C

A bicyclist started from rest along a straight path. After 2.0 s, his speed was 2.0 m/s. After 5.0 s, his speed was 8.0 m/s. What was his acceleration during the time 2.0 s to 5.0 s?
Answers
Acceleration is the change in velocity over time. We can calculate the acceleration of the bicyclist during the time 2.0 s to 5.0 s using the formula acceleration = (final velocity - initial velocity) / time.
The initial velocity of the bicyclist at 2.0 s is 2.0 m/s and the final velocity at 5.0 s is 8.0 m/s. The time interval between 2.0 s and 5.0 s is 3.0 s.
Substituting these values into the formula, we get acceleration = (8.0 m/s - 2.0 m/s) / 3.0 s = 6.0 m/s / 3.0 s = 2.0 m/s^2.
So, the acceleration of the bicyclist during the time 2.0 s to 5.0 s was 2.0 m/s^2.

Hence t = 18.7 ×sin49°/ 9.8 = 1.44s

Two charges q1 and q2 exert a force of 20 N on each other. If the charge of q1 is doubled, what will the new force be? 1) 40N 2) 80N 3) 20 N 4) 10 N
Answers
Given :
Two charges q1 and q2 exert a force of 20 N on each other.
To Find :
If the charge of q1 is doubled, what will the new force be?
1) 40 N 2) 80 N 3) 20 N 4) 10 N
Solution :
We know, electrostatic force between two charges is given by :
\(F = \dfrac{kq_1q_2}{r^2}\)
Here, F = 20 N.
\(20 = \dfrac{kq_1q_2}{r^2}\)
Now, if \(q_1\) is doubled :
\(F'= \dfrac{k(2q_1)q_2}{r^2}\\\\F'= 2\dfrac{kq_1q_2}{r^2}\\\\F'= 2\times F\\\\ F'= 2\times 20 \ N\\\\F'= 40 \ N\)
Therefore, if the charge of q1 is doubled, new force will be 40 N.

Planet a exerts a force on planet b. What can be said about the magnitude and direction of the gravitational force planet b exerts on planet a?
Answers
Answer:
Explanation:
According to Newton's Law of Gravitation, the gravitational force between two objects is always mutual, meaning that the force that one object exerts on the other is equal in magnitude but opposite in direction.
This means that if planet A exerts a gravitational force on planet B, then planet B will also exert a gravitational force on planet A. The magnitude of this force will be equal to the magnitude of the force that planet A exerts on planet B, but the direction will be opposite.
For example, if planet A exerts a gravitational force on planet B that is pulling planet B towards planet A, then planet B will also exert a gravitational force on planet A that is pulling planet A towards planet B. The magnitude of these two forces will be equal, but the directions will be opposite.
