Answer:
Placed the semicircular plastic block on the centre of a blank sheet of paper. Traced its outline and indicated the centre of the flat side
Explanation:
Answer:
Explanation:
The longer arm means the force needed to create the required torque is lower than for the short handled spanner.
τ = FR
Answer:
<em>The Strength of the electric field produced = 2 × 10⁷ N/C</em>
Explanation:
<em>Electric Field:</em> This is defined as the region where an electric force is experienced.
<em>Electric Field Strength: </em><em>The intensity of an electric field at any point is defined as the force per unit charge which it exert at that point. It direction is that of the force exerted on a positive charge.</em>
<em>It is represented mathematically as,</em>
<em>E = F/Q ................................. Equation 1</em>
<em>Where E = Electric field strength, F = electric force, Q = test charge.</em>
<em>Given: F = 3.2 × 10⁻⁴ N, Q = 1.6 × 10⁻¹¹ C</em>
<em>Substituting these values into equation 1</em>
<em>E= 3.2 × 10⁻⁴/1.6 × 10⁻¹¹ </em>
<em>E= 2 × 10⁷ N/C</em>
<em>Thus the Strength of the electric field produced = 2 × 10⁷ N/C</em>

please send the pic again it is not clear
Potential energy is the
energy that can be stored in a system when certain types of forces act between its components. Kinetic energy is the
energy associated with the motion of an object. According to conservation of energy, the total energy of an isolated system remains constant , energy may change from one form to another form within a system. Loss in potential energy is converted into kinetic energy and vice versa. Example is roller coaster. At the top most point of the track, all the potential energy is stored in the cart. As the cart moves towards bottom most point, potential energy converts into kinetic energy but the total energy of the system remains constant. i.e
( initial potential energy + initial kinetic energy = final potential energy + final kinetic energy). Hope this helps!
