Which of these is NOT a line on the tennis court?
Base line
Service line
Side line
Front line
Answer:
The answer would be Front Line
The base line, service line, and the side lines are the part of the tennis court however front line is not a part of the tennis court. Thus, the correct option is D.
What are the specifications of Tennis Court?
A tennis court is a 78ft long court, with a service line of 21ft from the net. The courts for singles tennis matches are 27ft wide in dimension, while the doubles matches courts are 36ft wide. The total playing area in tennis for a singles court is 2,106ft² and 2,808ft² for a doubles court.
The basic and important parts of a tennis court in both singles and doubles are the baseline, the center mark, the sidelines, the service lines, and the service boxes. The baseline is the boundary line at the ends of the tennis court, and the sidelines are the lines which mark the boundary line between in-bounds and out-of-bounds for both singles and doubles play.
Therefore, the correct option is D.

How do you increase the potential energy between two south magnetic
poles?
Answer:
A south pole of one magnet can approach the north pole of another. The magnetic fields are aligned. This makes an attractive force between the two magnets. The farther apart they are, the higher their potential energy.

Explanation:
What is the kinetic energy of a
54 kg person, diving into a pool
at a speed of 30 m/s?
Answer:
Explanation:
Formula
KE = 1/2 m v^3
Givens
m = 54 kg
v = 30 m/s
Solution
KE = 1/2 54 * 30^2
KE = 1/2 54 * 900
KE = 27 * 900
KE = 24300 Joules
A tuna traveling at 12 m/s starts to decelerate steadily. It comes to a complete stop in 10 seconds. What is its acceleration?
Answer:
a = -1.2 m/s^2
Explanation:
Vi = 12 m/s
Vf = 0 m/s
t = 10 s
Plug those values into the following equation:
Vf = Vi + at
0 = 12 + 10a
---> a = -1.2 m/s^2
explain electrostatic force
Answer:
Electrostatics is a branch of physics that studies electric charges at rest. Since classical physics, it has been known that some materials, such as amber, attract lightweight particles after rubbing. The Greek word for amber, or electron, was thus the source of the word 'electricity'.

The work done in lifting a brick of mass 2kg through a height of 5m above the ground will be
(A)2.5J
(B)10J
(C)50J
(D)100J
Answer:
D. 100 J
Explanation:
Given
Mass (m) = 2 kg
Height (h) = 5 m
Acceleration due to gravity (g) = 10 m/s²
Now
Work done(W)
= m * g * h
= 2 * 10 * 5
= 100 Joule
Hope it will help :)❤
The work done in uplifting a brick having a mass of 2kg along with a height of 5m above ground level would be:
D). 100 J
Given that,
Mass of the brick [tex]= 2Kg[/tex]
Height of the brick [tex]= 5m[/tex]
As we know,
Work Done (W) [tex]= mgh[/tex]
where
m = Mass
g = Acceleration due to gravity
h = height
A.T.Q.
By substituting the given values, we get;
[tex]Work Done (W)[/tex] [tex]= 2[/tex] × [tex]10[/tex] × [tex]5[/tex] (taking [tex]g = 10 m/s^2[/tex])
[tex]= 100 J[/tex]
Thus, the work done is 100 J and hence, option D is the correct answer.

Answer:
D. 1R=1r1+1r2+1r3
Explanation:
If three components are arranged to form a parallel circuit, and the individual resistance of these components are r1, r2, and r3 respectively, the formula for finding the total resistance R is: 1R=1r1+1r2+1r3.
if the reference point changes, the
_____ of position changes, but the actual position does not change
Answer:
description
Explanation:
Motion can be defined as a change in the location (position) of a physical object or body with respect to a reference point.
This ultimately implies that, motion would occur as a result of a change in location (position) of an object with respect to a reference point or frame of reference i.e where it was standing before the effect of an external force.
Mathematically, the motion of an object is described in terms of acceleration, time, distance, speed, velocity, displacement, position, etc.
A reference point refers to a location or physical object from which the motion (movement) of another physical object or body can be determined.
For example, a point on a map is considered to be a reference point because it represents the starting point of an object or person in motion.
If the reference point changes, the description of position changes, but the actual position does not change.

Para pagar la entrada al circo y comprar palomitas: Daniela y María van a cooperar con $65.50 cada una y Francisco y Javier con $69.50 cada uno. ¿Cuánto dinero van a reunir?
Answer:
Reunirán $270.
Explanation:
Para pagar la entrada al circo y comprar palomitas Daniela y María van a cooperar con $65.50 cada una. Entonces para calcular el dinero que van a reunir entre ambas debes sumar lo que aporta cada una:
$65.50 + $65.50= $131
Por otro lado, Francisco y Javier van a cooperar con $69.50 cada uno. De igual manera, para calcular el dinero que van a reunir entre ambos debes sumar lo que aporta cada uno:
$69.50 + $69.50= $139
Para conocer el dinero total recaudado, debes sumar lo que aportan tanto ellas como ellos. Esto es:
$131 + $139= $270
Reunirán $270.

A man stands in front of a vertical plane mirror which is fixed on a
wall as shown in the diagram below. The image formed by the
mirror is also shown.
The man looks at the image of his feet.
a. Complete the ray diagram to show how the man is able to see the
image of his feet in the mirror.
b. What is the purpose of the normal line in the diagram?
c. State which angle does x represent.
d. What's the type and direction of the image formed by the mirror?
Answer:
a) ray horizontal and ray leaves his feet
b) The normal line respect to which the angles are measured,
c) The angle x is the reflected angle
d) virtual image, right image
Explanation:
a) To complete the rays, you must draw a horizontal ray at the height of the man's head, this ray touches the mirror perpendicularly, therefore it bounces in the same direction.
The other ray leaves his feet and touches the mirror at one point, it is reflected with the same angle, by the law of reflection and reaches the eyes of man, the brain creates an extension of this ray and at the point of the floor creates the image point.
b) The normal line is a line perpendicular to the surface with respect to which the angles are measured,
c) The angle x is the reflected angle, which is equal to the incident angle according to the law of reflection
d) The image is formed by the prolongation of the rays of light, therefore it is a virtual image and as it has the same direction of the man it is a right image
