Cricket bat uses one common law of physics

When a ball hits the bat with some velocity ,the cricket bat should hit with some more velocity to get greater impact velocity to move the ball somewhere .

When the  distance between the charges is doubled, the electrostatic force between the charges will reduce by quarter.

The electrostatic force between two point charges is calculated using Coulomb's law;

[tex]F = \frac{kq^2}{r^2}[/tex]

where;

When the distance between the charges is doubled

[tex]F = \frac{kq^2}{(2r)^2} \\\\F = \frac{kq^2}{4r^2}\\\\F = \frac{1}{4} (\frac{kq^2}{r^2} )[/tex]

Thus, when the  distance between the charges is doubled, the electrostatic force between the charges will reduce by quarter.

Based on the forces acting on the axes, the resultant moments will be (345, 400, 600 N·m)

= F₃ x 3

= -115 x 3

= -345 N·m

= F₁ x 2

= -200 x 2

= -400 N·m

= F₄ x 2

= -300 x 2

= - 600 N·m

A 5kg object has a kinetic energy of 250J. Find the speed of the object by rearranging the formula :[tex]\sf{ KE=v^2\dfrac{m}{2}}[/tex]

Kinetic energy of an object is the energy possessed by the virtue of its motion.

Kinetic energy is given by:

[tex] \quad\hookrightarrow\quad{\pmb{ \sf {KE=\dfrac{mv^2}{2} }}}[/tex]

Here, we are given that:

By using the given formula:

[tex] \implies\quad \sf{ KE =\dfrac{mv^2}{2}}[/tex]

[tex] \implies\quad \sf{ 250 = \dfrac{5\times v^2}{2}}[/tex]

[tex] \implies\quad \sf{\dfrac{ 5}{2}\times v^2 = 250}[/tex]

[tex] \implies\quad \sf{ v^2 =250\times \dfrac{2}{5}}[/tex]

[tex] \implies\quad \sf{v^2 =\cancel{ \dfrac{500}{5}} }[/tex]

[tex] \implies\quad \sf{v^2 = 100 }[/tex]

[tex] \implies\quad \sf{ v =\sqrt{100}}[/tex]

The statement that correctly describes the direction of conventional current in the circuit is : ( C ) current is directed from A to B to C to D

conventioanl current is simply the flow of protons from the positive terminal of the voltage source ( battery ) to the negative terminal of the battery. Also conventional current is the charge transferred in a given direction per unit time. for a conventional current the charge carrier is irrelevant.

Hence we can conclude that the direction of conventional current in the circuit is : current is directed from A to B to C to D.

Answer:

a. How much force is required to lift a box of weight 100 N upwards with a constant acceleration of 6.0 m/s2?

b. How much upwards force is required to lower the same box with a downward acceleration of 3.0 m/s2?

a. As the box weighs 100 N, its mass is 100 N / 9.8 ms-2  =  10.2 kg.  To have an upward acceleration of 6.0 m/s2, there must be a net upward force of F =ma  =  10.2 kg x 6.0 m/s2 =  61.2 N.  The total upward force must be equal have a magnitude to overcome the downward force of gravity and to provide for the upward acceleration  Ftotal up = 100 N + 61.2 N  =  161.2 N.

b. There must be a net downward force F = ma = 10.2 kg x 3.0 m/s2  =  30.6 N upward.  There must be an upward force to counteract the downward force of gravity so that the resultant will be 30.6 N.  The equation necessary for this is 100 N - upward force =  30.6 N.  Solving for the upward force gives  69.4 N.

'The normal is a line perpendicular to the surface of the mirror'.This is the correct statement that corrects an error on the site.

The law of reflection specifies that upon reflection from a downy surface, the slope of the reflected ray is similar to the slope of the incident ray.

The reflected ray is consistently in the plane determined by the incident ray and perpendicular to the surface at the point of reference of the incident ray.

When the light rays descend on the smooth surface, the angle of reflection is similar to the angle of incidence, also the incident ray, the reflected ray, and the normal to the surface all lie in a similar plane.

Hence 'The normal is a line perpendicular to the surface of the mirror'.This is the correct statement that corrects an error on the site

Therefore ,m1c1 ΔT = m2c2ΔT

Where m1 is 25g and m2 is 200g

so , 25c1 = (200+10)(22-2)

      25c1 = 420
