How does physical activity affect your mental health? Regular exercise can have a profoundly positive impact on depression, anxiety, and ADHD. It also relieves stress, improves memory, helps you sleep better, and boosts your overall mood. And you don’t have to be a fitness fanatic to reap the benefits. What are the negative effects of […]
Why do shoots grow up and roots grow down?
Why do shoots grow up and roots grow down? Roots respond to gravity and shoots grow towards sunlight. Roots – Roots grow down because the root respond to gravity by releasing the chemicals that prevent growth on the lower side,thus turning the root downwards. Why do shoots grow away from gravity? The roots grown downward […]
Can humans see microwaves?
Can humans see microwaves? The human retina can only detect incident light that falls in waves 400 to 720 nanometers long, so we can’t see microwave or ultraviolet wavelengths. This also applies to infrared lights which has wavelengths longer than visible and shorter than microwaves, thus being invisible to the human eye. Why can’t our […]
What is definition of inertia?
What is the acceleration in a straight line?
What is the purpose of a distance-time graph?
What is the purpose of a distance-time graph? A distance-time graph shows how far an object has travelled in a given time. It is a simple line graph that denotes distance versus time findings on the graph. Distance is plotted on the Y-axis. What is the distance between two nodes in a graph? In the […]
What is the loss of traction most difficult to identify quickly?
What is the loss of traction most difficult to identify quickly? Signs of hydroplaning – this is the most difficult loss of traction for a driver to recognize • Water standing on the roadway. How do you fix loss of traction? If You Lose Traction Gently reduce pressure on brakes – if on ice, push […]
Do noise Cancelling headphones block all sound?
Do noise Cancelling headphones block all sound? Active noise-canceling headphones can do everything that passive ones can do — their very structure creates a barrier that blocks high-frequency sound waves. They also add an extra level of noise reduction by actively erasing lower-frequency sound waves. Is Noise Cancelling bad for ears? So, Is Noise-Canceling Safe? […]
What is the coefficient of volume expansion?
What is the coefficient of volume expansion? An object of volume V expands to V+ΔV when temperature is increased by ΔT, then volume expansion coefficient αv is given by. αv = (ΔV/V) / ΔT. What is a coefficient of thermal expansion? THE COEFFICIENT OF LINEAR thermal expansion (CTE, a, or a1) is a material property […]
