one of the property of radio waves is that they have long wavelength. due to their long wavelength , they undergo diffraction around the mountains and thus the waves spread around the mountain. this makes them eligible to be used for long distance communication. they can coded and decoded also . that is why they are used in television and radio system
Given data:
The area of the hydraulic press is,
The applied force is,
The pressing force on the large piston is
Given hydraulic press works on Pascal's law principle.
From the Pascal's law, the equation can be given as,
Here,
is the area of the larger piston.
Substituting the values in the above equation, we get:
Thus, the area of the large piston is
Answer:
350 Kg
Explanation:
We use the Work Formula:
W = Force . Distance
33.000 Joules = Force . 6
Force = 5500 Newtons
Force = Mass . Acceleration
5500 = Mass . 10
Mass = 550
550 - 200 = 350 Kg
Answer:108.71 mL
Explanation:
Given
Volume of sample V=150 mL
concentration of sucrose solution 35 % w/w i.e. In 100 gm of sample 35 gm is sucrose
specific gravity =1.115
Density of solution
Thus
mass of sample
mass of sucrose
mass of Water
Volume of water
Answer:
A) When the baseball is rising
Explanation:
When an object like the baseball is thrown into the air, the kinetic energy is gradually converted into potential energy. When the baseball rises to its maximum height, the kinetic energy becomes zero and the kinetic energy is fully converted into potential energy.
