Un montacargas hidráulico es utilizado para levantar cajas con un peso de 1500 newtons sobre una superficie de 20 cm al cuadrado
1 answer:
Answer:
150 N
Explanation:
The question says that, "A hydraulic forklift is used to lift boxes with a weight of 1500 newtons over a surface of 20 cm squared. What is the force applied to a base of 2 cm squared?"
Given that,
Force applied, F₁ = 1500 N
Area, A₁ = 20 cm²
We need to find the force applied to a base of 2 cm². Using Pascal's law to find it such that,
So, the required weight is 150 N.

Given data:
first case
Distance of electric field from center of sphere is r_1 <R
Electric field at r_1< R
second case
Distance of electric field from centre of sphere is r_1 < 2R
Electric field at r_1< 2R
so, we have
Answer:
Explanation:
give data:
inside diameter = 5.0 cm
charge q = 0.25 nC
Outside diameter = 15 cm
potential V at inside sphere is =
potential V at outside sphere is =
k is constant whose value is =
then potential difference between two point is
Answer:
Maximum speed, v = 36 m/s
Explanation:
Given that,
The radius of the curved road, r = 120 m
Road is at an angle of 48 degrees. We need to find the maximum speed of stay on the curve in the absence of friction. On a banked curve, the angle at which it is cant is given by :
g is the acceleration due to gravity
v = 36.13 m/s
or
v = 36 m/s
So, the maximum speed to stay on the curve in the absence of friction is 36 m/s. Hence, this is the required solution.
