Hari drag a load of 60 kg along a distance of 12 metre what amount of work does he do also mention the type of work​
Vlada [557]

Answer:

W = 7056  J

Explanation:

Given that,

Mass of a load, m = 60 kg

Distance moved, d = 12 m

We need to find the amount of work. The work done by an object is given by :

W = Fd

So,

W = mg×d

W = 60 kg × 9.8 m/s²×12 m

W = 7056  J

So, the amount of work done is 7056  J.

The electric potential in a volume of space is given by V(x, y, z) = 2x2 - 3y2 + 5z.
vekshin1

The electric field at (x,y,z) its equal to the negative of the gradient if the electric potential.

We have

V(x, y, z) = 2x² - 3y² + 5z

so

E(x, y, z) = -grad(V) = -(dV/dx i + dV/dy j + dV/dz k)

where d/d(variable) is meant to be a partial derivative with respect to that variable. The partial derivatives are

dV/dx = 4x

dV/dy = -6y

dV/dz = 5

and so the electric field at any point is

E(x, y, z) = -4x i + 6y j - 5k

and at (3, 4, 5) it is

E(3, 4, 5) = -12i + 24j - 5k

You are using an 8 th order low-pass filter. Determine the roll-off achievable in the stop band, in dB/dec, and determine the ph
Andreas93 [3]

Answer: The complexity of filter is the order of the filter. Greater the order of the filter, more efficient the filter is. Roll of value of one filter is 20dB/dec. So the roll-off value of 8th order filter is 160dB/dec. 8th order filter is more efficient than the second order low-pass filter.
