#2
As it is given here
initial speed is
After 4 seconds the final speed is
so here we can use the formula of acceleration using kinematics
so here it will accelerate at 2 m/s^2 rate.
#3
As it is given here
initial it starts from rest
After 2.5 seconds the final speed is
so here we can use the formula of acceleration using kinematics
so here it will accelerate at 6 m/s^2 rate.
#4
i think question is not correct as in first line it is saying about a bag of trash and then in next line it is asking for the position of Jumper and bridge.
<span>If there isn't any force then the normal contact force will be
N=m*g=7.5*9.81=73.58N
which is 73.58-23=50.58N less
so, there the person must pull at 23 degree upward
break down the tension in two components, vertical and horizontal.
vertical tension= 50.58=T*sin23
T=50.58/sin23=129.45N</span>
Answer:
The magnification produced by a plane mirror is +1
means then the size of the image is equal to the size of the object. If m has a magnitude greater than 1 the image is larger than the object, and an m with a magnitude less than 1 means the image is smaller than the object.
Correct option B
Transverse waves are those waves whose particles vibrate perpendicular to the direction of wave.

b
Explanation:
From the question we are told that
The mass of the person is 
The speed of the person is 
The energy of the proton is 
Generally the de Broglie wavelength is mathematically represented as
Here h is the Planck constant with the value
So
=>
Generally the energy of the proton is mathematically represented as
Here 
is the mass of proton with value 
=> 
=> 
=> 
So
so 
=>
