Answer:
t = 3w/gk
y = w²/gk²(2+e^-gkt/t)
Explanation:
The detailed step by step solution can be found in the attachment below.
Vt = W/k. It is the velocity of the body when the drag force = the weight of the particle.
I steps have been explaine6in the attachments below.
For transverse waves, the waves move in perpendicular direction to the source of vibration. For longitudinal waves, the waves move in parallel direction to the source of vibration . They are similar in the sense that energy is transferred in the form of waves.
Answer:
v=14.14 m/s
t=1.141 s
Explanation:
Given that
h = 10 m
Initial velocity ,u = 0 m/s
We know that acceleration due to gravity g= 10 m/s²
Lets take final velocity = v
Final velocity v is given as
v² = u²+ 2 g h
v²= 0² + 2 x 10 x 10
v²= 200
v=14.14 m/s
Time taken t is given as
v= u + a t
a=acceleration
t=time
Now by putting the values in the above equation we get
14.14= 0 + 10 x t
14.14 = 10 t
t=1.141 s
Answer:
a) increases
Explanation:
The increase in temperature causes the particles to move much faster. This in turn effects the collision rate of the particle which causes the chemical reaction. Thus the rate of chemical reaction increases.
So, we conclude that the rate of a chemical reaction is directly related to temperature. With increase in temperature there is an increase in the reaction rate and vice versa.

The Si units of all the left measurements are true thus, in length the typical
and standard SI unit is meter. SI units, also called as International Standard
of Units, is composed of the following systematized units of physical measure
which include, mole (amount of substance), candela (luminous intensity), kelvin
(temperature), ampere (electric current), second (time), kilogram (mass), and meter
(length). Hence, these measures spheres in multiplication or division by power
of 10, increase or decrease in measure.</span></span>
