A motorcycle together with its Rider with 150 kg how much work is needed to set its movement at 15 metre per second.​
AVprozaik [17]

Answer:

W = 16875 J

Explanation:

We have,

Mass of a motorcycle together with its rider is 150 kg

It is required to find the work is needed to set its movement at 15 metre per second. The work done is given by :

W=\dfrac{1}{2}mv^2

Plugging all the values in above formula such that :

W=\dfrac{1}{2}\times 150\times (15)^2\\\\W=16875\ J

So, the work of 16875 J is needed.

A uniform electric field with a magnitude of 125 000 N/C passes through a rectangle with sides of 2.50 m and 5.00 m. The angle b
jeyben [28]

Answer:

6.60\cdot 10^5 Nm^2/C

Explanation:

The electric flux through the rectangle is given by

\Phi = E A cos \theta

where

E is the electric field strength

A is the area of the rectange

\theta is the angle between the direction of the electric field and of the vector normal to the plane of the rectangle

In this problem we have

E = 125 000 N/C

The area of the rectangle is

A=2.50 m \cdot 5.00 m=12.5 m^2

and the angle is

\theta=65.0^{\circ}

so, the electric flux is

\Phi = (125,000 N/C)(12.5 m^2)(cos 65^{\circ})=6.60\cdot 10^5 Nm^2/C
