the answer would be the last one because kinetic energy is something in motion.
hope it helps.
Answer:
False
Explanation:
The force of an object does not depend on the dimensions of the said object. The formula for force is
F = Ma, where
m = mass and a = acceleration
The force is dependent on the size of the object and its acceleration. An object 2m by 5m running at a acceleration of x m/s² and weighing y kg will have the same force as another object 15m by 25m running at the same acceleration x m/s² and weighing y kg
Answer:
1.196 m
Explanation:
Given the wave equation :
y= 0.05 cos(5.25x-1775t)
Recall the general traverse wave relation :
y(x, t) = Acos(kx - wt)
A = Amplitude
To Obtian the wavelength ;
We compare the both equations :
Take the value of k ;
kx = 5.25x
k = 5.25
Recall;
k = 2π/λ
5.25 = 2π/λ
5.25λ = 2π
λ = 2π / 5.25
λ = (2 * 3.14) / 5.25 = 1.196 m
Answer:
1.14*10^-3m
Explanation:
We know that
Volume= mass/ density
But
Area x depth= mass/density
πr²*depth= mass/density
r²=m/πdp
So
r= √0.35/3.142*0.085*1000
r= 1.14*10^-3m
<span>It rather depends on your definition of "machine". The normal physics set of simple machines - levers, pulleys, ramps all give you increased force at the expense of reduced speed or increased speed at the expense of reduced force.
So, no - by definition a machine is an arrangement for multiplying one while paying the cost by reducing the other. You are looking at an example of the Conservation of Energy... one of the giant rules we are pretty sure cannot be violated.</span>
