A car of mass 1500kg has a maximum speed of 150km/hrs on a level road when working at a maximum power against resistance force of 60N. 1. Find the maximum power of engine.
2. Find the acceleration of the car when it travels at 60km/hrs with the engine working at a maximum power assuming that the resistance of the motion remain constant.​

i think they are all correct

explanation:

they seem good

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
