Answer:
Explanation:
the slits spacing, d = 0.21 mm
distance of screen, D = 61 cm
The condition for minima is given as
So, first minima, n = 0
fifth minima, n = 4
For small angle
From the figure:
Answer:
Frequency and tfcvvbyfgffhhi
A
A is incorrect. It depends very much on which gas it is. O2 has vastly different properties than F2
B
Yes it can. The molar mass of oxygen is 2 * 16 = 32
The molar mass of F2 = 2*9 = 18
C
The molar mass is independent of temperature So C is false
D
is True
B and D are both true.
Answer:
The gravitational acceleration is same for all objects.
a = b = c = d
Explanation:
Acceleration due to gravity or gravitational acceleration is the force exerted by Earth on unit mass of an object.
Acceleration due to gravity doesn't depend on the height of the object when the height is object is near to the surface of the Earth. Only when the height is comparable to the radius of the Earth, the value of gravitational acceleration changes.
But for the objects here, the gravitational acceleration is independent of the mass or height of the objects and has a constant value of 9.8 m/s².
Therefore, the gravitational acceleration of all the objects is same.
If 'a', 'b', 'c', and 'd' represent gravitational accelerations of objects 'a', 'b', 'c', and 'd' respectively, then a = b = c = d.
Answer:
<h2>1320 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 55 × 24
We have the final answer as
<h3>1320 N</h3>
Hope this helps you
