Both rocks hit the ground at the same time and at the same distance from the base of the cliff. Option A is correct.
What is speed ?Speed is defined as the rate of change of the distance or the height attained. it is a time-based quantity. it is denoted by u for the initial speed while u for the final speed. its SI unit is m/sec.
If the resistance is ignored, things falling near the Earth's surface have the same estimated acceleration due to gravity of 9.8 meters per second.
As a result, the objects' acceleration is the same, and their velocity is growing at a consistent pace.
So that both rocks hit the ground at the same time and at the same distance from the base of the cliff.
Hence, option A is correct.

This is so you can reach the gas petal, break petal, steering wheel, (and other things) easier so you won't have to lean forward and it makes it easier for when you're driving. Especially if you need to quickly press your breaks, you'll be able to do this a lot faster if you're closer to them than if you had to reach in order to do so.

[tex] \textsf{How many images will be formed when two plane } [/tex][tex] \textsf{mirrors are inclined on each other by an angle of 60° ?} [/tex]
[tex] \texttt{[ Need explanation ]} [/tex]
[tex] \bold{\underline{\underline{\underbrace{Answer}}}} [/tex]
5 images
Explanation:
⠀
⠀
⠀⠀⠀⠀▦ NoteWhat is reflection of light?
The reflection of light is the phenomenon in which the rays of light falls on the object and change it's path.
⠀
How image is formed in plane mirror?
When you look at the mirror the image is formed behind the mirror and it is virtual. The light from the object which reaches the mirror gets reflected back.
⠀
⠀
⠀⠀⠀⠀SolutionThe formula to find the no. of images between the 2 plane mirror at any angle θ.
[tex] \sf No. \: of \: images = \frac{360 \degree}{ \theta} - 1[/tex]
According to the question the plane mirror is inclined at 60° angle.
Substituting the required values.
[tex] \sf \large \frac{ \cancel{360} \small \: \: 6}{ \cancel{60}} - 1 \\ \\ \sf \large 6 - 1 \\ \\ \boxed{ \frak{ \implies 5} }[/tex]
The 2 plane mirror will form 5 images inclined at 60° angle.
Line segment gj is a diameter of circle l. angle k measures (4x 6)°. circle l is inscribed with triangle g j k. line segment g j is a diameter. line segments g k and k j are secants. angle k has a measure of (4 x 6) degrees. what is the value of x? 21 24 32 44
The value of x in the given right triangle in a semicircle is determined as 21.
What is the measure of a triangle in a semicircle?The triangle in a semicircle is always a right angle triangle.
From the figure shown, we can say that the triangle G J K is right triangle and m<K = 90degrees.
Given that m<K = 4x + 6, we will can use the following equation to find the value of x as shown:
4x + 6 = 90
4x = 90 - 6
4x = 84
x = 21
Thus, the value of x in the given right triangle in a semicircle is determined as 21.

you are designing an airport for small planes. one kind of airplane that might use this airfield must reach a speed before takeoff of at least 27.8m/s and can accelerate at 2.00m/s a)if the runway is 150m long,can this airplane reach the required speed for take off?(in this case v=24.5 m/s) b) if not, what minimum length must the runway have(193m)
(a)The required speed for take off will be 24.49 m/sec.
(b)The minimum length must the runway have 193 m.
What is speed?Speed is defined as the rate of change of the distance or the height attained. it is a time-based quantity. it is denoted by u for the initial speed while v for the final speed. its SI unit is m/sec.
(a)The required speed for take off will be 24.49 m/sec.
From the Newtons third equation of motion;
[tex]\rm v^2 = u^2+2as \\\\ v=0+2 \times 2 \times 150 \\\\ v=\sqrt{600}\\\\ v=24.49 \ m/sec[/tex]
Hence, the required speed for take off will be 24.49 m/sec.
(b)The minimum length must the runway have 193 m.
From the Newtons third equation of motion;
[tex]\rm v^2 = u^2+2as \\\\ (27.78)^2 = 0+2\times 2 s \\\\\ s=192.93 \ m[/tex]

The minimum amount of water needed for bathing assuming the water begins at room temperature is 16.58kg.
What is thermal equilibrium?When two bodies at different temperature come into contact, they share the heat through conduction. After some time, temperature of both becomes equal. This condition is said to be a body in thermal equilibrium with other.
Heat gained by the water = heat lost by the ill person
m x Cw x ΔT = M x Cp x Δt
where, mass of person M = 80kg, Cp =specific heat of body =3470, specific heat of water Cw= 4186, then mass of water m will be
m x 4186 x (37-25) =- 80 x 3470 x (37-40)
m = 16.58kg
