Work is done when a motion resulted from the force being done by an object. The amount of work done is calculated by multiplying the force applied and the distance traveled. It is calculated as follows:
Work = Force x distance = 280 N x 5 m = 1400 J.
Here's the handy factoid I always carry around in my toolbox:
When the three dimensions of a solid object all change by a factor of ' K ' . . . .
-- the surface area of the object changes by a factor of K²
-- the volume of the object changes by a factor of K³ .
So I guess if the surface area increases by 3, that means each linear dimension increased by √3, and the volume has to increase by (√3)³ .
That's 5.196 times the dog's original volume.
(And so does his weight. The poor thing is staggering around wondering what was in that last bowl of kibble that he inhaled.)
The force on one end of the trough is 5.4 X 10⁵ N
<u>Explanation:</u>
The triangle is equilateral which means all the interior angles are 60° and the sides are 6m long.
According to the figure,
AI / 8 = sin (60) = √3/2
AI = 4√3
The depth of the water is AI = 4√3
The interval becomes, | 0 , 4√3|
w = 2JK
(the hydrostatic force acting on the strip is the product of the pressure and the area)
where.
ρ = 875 kg/m³
g = 9.8m/s²
d = depth ( d = y')
limit is 0 → 4√3
On solving the equation, we get the value of limit as 32√3
Therefore, the force on one end of the trough is 5.4 X 10⁵ N
Answer:
a coil rotating in a magnetic field to change its flux
Answer:
The time is 0.6 sec.
Explanation:
Given that,
Acceleration of car = 7.2 m/s²
Speed = 4 m/s
We need to calculate the time
Using equation of motion
Where, u = initial velocity
v = final velocity
a = acceleration
t = time
Put the value in the equation
Hence, The time is 0.6 sec.
