You are driving to your grandparents which is 95km away. If I drive at an average speed of 85km/h, how long will it take to get there?

Time = 1.118 hours

Explanation:

Given the following data;

Distance = 95 km

Speed = 85 km/h

To find how long will it take to get there;

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the formula;

Making time the subject of formula, we have;

Substituting into the equation, we have;

Time = 1.118 hours

the device is called “ rocket engine”

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
