The torque on the lever, with a 15 N force applied perpendicular at 2.0 m from the pivot point, is 30 N·m.
The torque on a lever is calculated by the formula T = rF sin θ, where T is torque, r is the distance from the pivot point to the point where the force is applied (lever arm), F is the force applied, and θ is the angle between the lever arm and the direction of the force. In this case, the force is applied at 90° to the lever arm, so the sin θ part of the formula is equal to 1. Therefore, the torque can be calculated by multiplying the force by the lever arm distance. With a force of 15 N applied perpendicular to the lever arm at a distance of 2.0 m from the pivot point, the torque on the lever would be 30 N·m (15 N x 2.0 m).

When the substance was tested in the lab it was seen that it maintains a unique shape, which is the differentiating property of solids. Also, they are very good conductors of electricity. Solid contains electrons, protons and neutrons this is a common thing which is found in every state of matter. This all details confirms that it will be solid.
2.5 × 10⁴ is the scientific notation for 0.00025. this is done by moving decimal to the first non zero number.
When a number is too big or too tiny to be readily stated in decimal form, or if doing so would involve writing down an exceptionally lengthy string of digits, it can be expressed using scientific notation. It is also known as standard form within the UK and scientific form, standard index form, and standard form. Scientists, mathematicians, or engineers frequently utilise this base ten notation because it may make some mathematical operations simpler. 2.5 × 10⁴ is the scientific notation for 0.00025. this is done by moving decimal to the first non zero number.
