Answer:

If the two forces applied to an object act in the same direction ,then the resultant force acting on the object is equal to the sum of two forces: When two forces act in the same direction their effective magnitude increases

The induced magnetic field at radial distance 4.0 mm from the central axis of a circular parallel-plate capacitor is 1.8 ✕ 10−7
wel

Answer:

\frac{dE}{dt}=2.07*10^{13}\frac{V/m}{s}

Explanation:

According to Gauss's law, the electric flux through the circular plates is defined as the electric field multiplied by its area:

\Phi=EA=E(\pi R^2)(1)

The magnetic field around the varying electric field of the circular plates is given by:

B=\frac{\epsilon_0 \mu_o}{2\pi r}\frac{d\Phi}{dt}(2)

Replacing (1) in (2) and solving for \frac{dE}{dt}:

B=\frac{\epsilon_0 \mu_o\pi R^2}{2\pi r}\frac{dE}{dt}\\\frac{dE}{dt}=\frac{2rB}{\epsilon_0 \mu_o R^2}\\\frac{dE}{dt}=\frac{2(4*10^{-3}m)(1.8*10^{-7}T)}{(8.85*10^{-12}\frac{C^2}{N\cdot m^2})(4\pi *10{-7}\frac{Tm}{A})(2.5*10^{-3}m)^2}\\\\\frac{dE}{dt}=2.07*10^{13}\frac{V/m}{s}

Given a force of 56N and an acceleration of 7m/s2, what is the mass?
bearhunter [10]
F = ma
You need to rearrange this equation to find mass so you would have the equation :
M = f/a
Input the numbers into the equation :
M = 56/7
M = 8

Explain how temperature changes affect the ice on a lake ?
KengaRu [80]
Well if it gets warmer the ice will weaken and if it gets hot enough will melt. Of course if the weather gets colder the ice will thicken.
