What keeps the moon moving in a circular motion? Gravitational attraction provides the centripetal force needed to keep planets in orbit around the Sun and all types of satellite in orbit around the Earth. The Earth’s gravity keeps the Moon orbiting us. It keeps changing the direction of the Moon’s velocity. What changes continuously in […]

Why do the bullet fired horizontally and the bullet dropped hit the ground at the same time?
Why do the bullet fired horizontally and the bullet dropped hit the ground at the same time? The fired bullet only experiences a horizontal force from the gun. The only vertical force acting on the fired bullet is gravity. Therefore, the fired bullet and the dropped bullet both experience the same exact downward force. This […]
How do plants maintain the amount of oxygen and carbon dioxide?
How do plants maintain the amount of oxygen and carbon dioxide? The balance of oxygen and carbondioxide is maintained in the atmosphere by the oxygen released by plants during photosynthesis and carbondioxide released by human,animals etc. The balance of oxygen and carbondioxide is made due to respreration and photosinthesis. What is the role of trees […]
Do sponges have a heart?
Do sponges have a heart? In summary, sponges – or poriferans – do not have a true circulatory system as most animals do.

Extrusive rocks are formed on the surface of the Earth from lava, which is magma that has emerged from underground. Intrusive rocks are formed from magma that cools and solidifies within the crust of the […]
How many times have gravitational waves been detected?
How many times have gravitational waves been detected? It is the collaboration’s second catalogue of events, following one published in December 2018 describing their first 11 detections. In all, the observation network has now observed 50 gravitational-wave events (see ‘Cosmic clashes’). How will gravitational waves reveal a hidden universe? With gravitational waves we can study […]
What is the difference between an air conditioner and a heat exchanger?
What is the difference between an air conditioner and a heat exchanger? With air conditioning, there is no concern about hot spots because cooling occurs at well below ambient temperatures. Heat exchangers effectively prevent hot spots even though the cooling is slightly above the ambient temperatures. What heat transfer mediums are utilized in a residential […]
