2.True
3. True
4. True
5. False
The strength of electromagnetic can be increased by increasing the number of wire around it
The path followed by a projectile is called its <em>trajectory. (C)</em>
In the most common school situation<em> </em>... <u>with</u> gravity but <u>without</u> air resistance, the trajectory of a projectile is the shape of an inverted parabola (nose pointing up). That's the result of constant horizontal velocity and accelerated vertical velocity.
To answer this question, we would need the formula for the kinetic energy which is Kinetic Energy = ½ x m x v^2
Where the following means: m is the mass of the object and v is the velocity
So At 7 m/s: Kinetic Energy = ½ x 5 x 7^2 = 122.5 J is the answer
