any two uses of good conductor of heat are
aluminium, cooper, metal are good conductor of heat and they are used for making utensils.
gold, silver, are also good conductor of heat they are used for making jewelleries.
Answer:
The wavelength of wave is 2.78 m.
Explanation:
Frequency of a wave is 90 Hz
Speed of a wave is 250 m/s
It is assume to find the wavelength of wave. The formula of speed is given by :
So, the wavelength of wave is 2.78 m.
Weight = (mass) x (acceleration of gravity).
When I calculate the weight of the 81.6 kg, the number I use for gravity
is 9.807 m/s². That gives a weight of 800.25 N, so I think that's where the
question got the crazy number of 81.6 kg ... whoever wrote the problem
wants the hay to weigh 800 N, and that's what I'll use for the weight.
The forces on the bale of hay are gravity: 800N downward, and the
guy on the truck with the pitchfork pulling upward on it with 850 N.
The net force on the bale is (850 - 800) = 50 N upward.
Use Newton's second law of motion: (Net force) = (mass) x (acceleration)
Divide each side by 'mass' :
Acceleration = (net force)/(mass)
On the hay wagon,
Acceleration = (50 N upward) / (81.6 kg) = <em>0.613 m/s² upward</em>

Please see list of answers below
Explanation:
If the FORCE applied to the car doubles, then following the equation F = m * a , the acceleration will DOUBLE as well.
The mass of the car stays the SAME.
And the velocity of the car will INCREASE with time based on the formula of kinematics of an accelerated object:
v(t) = vi + a * t
