The maximum mass of a load that can be lifted by the jack and the distance covered are:
m = 160.2 Kg
h = 25 cm
Given that a certain hydraulic jack is used for lifting load. a force of 250N is applied on a small piston with a diameter of 80cm while the diameter of the larger piston is 2.0m.
The parameters given are
= 250
= Area of the small piston = π
= 22/7 x 
= 0.5 
= ?
= Area of the large piston = π
= π x 1
= 3.14
To calculate the force on the large piston, we will use the below formula
/ = /
Substitute all the parameters into the equation
250/0.5 = /3.14
= 1570 N
To calculate the maximum mass of a load that can be lifted by the jack, let us apply Newton second law
F = mg
1570 = 9.8m
m = 1570/9.8
m = 160.2 Kg
.(take g=9.81ms^-2)
If the applied force moves through a distance of 25cm, the distance through which the load is lifted will be
/ 0.25 = / h
250/0.125 = 1570/3.14h
make h the subject of the formula
6280h = 1570
h = 1570/6280
h = 0.25 m
Therefore, the distance through which the load is lifted is 25 cm

Answer: we need B/√2 for having twice the energy i.e 0.17B
Explanation:
This is actually a simple one, so i will guide you through it.
We know that Energy here means Kinetic Energy (K.E)
and the expression is given thus;
Energy = 1/2 mv2
and velocity v = E/B
let us make x the energy intially, foe electric field E, magnetic field B, mass m
so, x = 1/2 m (E/B)2
we have to find magnetic field for which twice the energy so , let magnetic field be y, so
2x = 1/2m(E/y)2
y = B/√2 = 0.17B
therefore, we need B/√2 for having twice the energy
cheers i hope this helps!!!!
Answer:
The image shows an object at rest, then a force pushes the car into the water. Newton's First Law describes that objects at rest remain at rest, and objects at motion remain at motion, unless they are bothered by a force. This law comes into play with the image because the object is first seen at rest, on the top of another object. Then it is seen falling, and is now in motion at it descends into the water. Newton's Second Law, F = MA, is seen in the image is the object accelerates into the water from the force. Newton's Third Law, which states 'for every action there is an equal but opposite reaction', is in this image as the object is falling, then makes contact with the water.
Explanation: Newton's Laws
Explanation:
to calculate the acceleration we use this formula
force=mass × acceleration
F = M × A
we are given the value of force(F) which is 52 and mass(M) which is 4
to find the acceleration we just make A the subject of formula
A = F/M
A=52/4
A =13m/s²
