Can I put a 40W bulb in a 60W socket? Yes you can, the light output will be 33% less but then you will use less energy. light fittings should be labelled to state the maximum safe wattage bulb which can be fitted. Never under any circumstances exceed the maximum but lower is fine. How […]
How do you find the velocity of an object?
How do you find the velocity of an object? Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time […]

What is called where the muscle build strength against resistance? Resistance training (also called strength training or weight training) is the use of resistance to muscular contraction to build the strength, anaerobic endurance and size of skeletal muscles.

What are solar collector explain with suitable diagram?
What are solar collector explain with suitable diagram? A diagram of a line focus solar collector. These collectors, sometimes known as parabolic troughs, use highly reflective materials to collect and concentrate the heat energy from solar radiation. These collectors are composed of parabolically shaped reflective sections connected into a long trough. What are the materials […]
What is the difference between lift and drag force?
What is the difference between lift and drag force? Lift is the force that acts at a right angle to the direction of motion through the air. Lift is created by differences in air pressure. Drag is the force that acts opposite to the direction of motion. Drag is caused by friction and differences in […]
