Actually Welcome to the Concept of the Ohms Law,
According to the Ohms law,
V = I*R, where, V = Voltage, I = Current, R = resistance,
so here given as, V = 240 V, I = 32 A,
so we get as, R = 240/32
R = 7.5 ohms,
===> The resistant R is ==> 7.5 ohms.
Answer:
Length of the arc of this sector, l = 14 cm
Explanation:
It is given that, the perimeter of a sector of a circle is the sum of the two sides formed by the radii and the length of the included arc.
Perimeter of sector, P = 28 cm
Area of sector,
According to figure,
2r + l = 28 ............(1)
Area of sector,
Where, is in radian and
Since,
Put the value of r in equation (1) so,
On solving above equation for l we get, l = 14 cm. So, the length of the arc of this sector is 14 cm. Hence, this is the required solution.
Acceleration of the ball is
Explanation:
The acceleration of the ball can be found by using Newton's second law of motion, which states that the net force acting on an object is equal to the product between the mass of the object and its acceleration:
where
F is the net force
m is the mass
a is the acceleration
For the ball in this problem, we have
m = 0.50 kg (mass)
F = 25 N (force)
thereofre, the acceleration of the ball is
