Answer:
Explanation:
ω = 2π/ T = 2π/ 3.01 = 2.087 rad/s
x(t) = 0.290sin2.087t
v(t) = 0.290(2.087)cos2.087t
a(t) = -0.290(2.087²)sin2.087t
With these three equations, you should be able to plug in what you know to find other values
Answer:
When the metal is dropped in the solution it turns blue to green because this forms iron sulphate solution and turns the metal copper
Iron sulphate + copper
Answer:
Explanation:
For an electromagnetic wave, the relationship between magnetic field amplitude and electric field amplitude is given by
where
E is the amplitude of the electric field
c is the speed of light
B is the amplitude of the magnetic field
For the electromagnetic wave in this problem, we have
E = 10 V/m is the amplitude of the electric field
So if we solve the formula for B, we find the amplitude of the magnetic field:
Answer:
The pressure is the measure of force acting on a unit area. Density is the measure of how closely any given entity is packed, or it is the ratio of the mass of the entity to its volume. The relation between pressure and density is direct. Change in pressure will be reflected in a change in density
