What are the similarities between Venus and Mars?
What are the similarities between Venus and Mars? Venus’s atmosphere is thick and dense, whereas that of Mars is light and tenuous. Despite the differences, the magnetometer instruments have discovered that the structure of the magnetic fields of both planets are alike. What characteristics do Venus and Earth share? Earth and Venus has similar size, […]
What does a negative angular acceleration indicate to you?
What does a negative angular acceleration indicate to you? Negative angular velocity(ω) means that the particle is revolving anticlockwise. Thus, negative angular acceleration(α) is a “push” in the anticlockwise direction. If α and ω have the same sign, the body will speed up, else slow down (and eventually go in reverse). Is clockwise positive or […]

What stops cells from growing?
What stops cells from growing? In the absence of sugar, TORC1s assemble into a tubular structure, rendering them inactive and thus cell growth stops. TORC1 is an enzyme complex that controls the normal growth of our cells; but, when too active, it can promote diseases such as cancer. How do you stop cells from dividing? […]
Does higher entropy mean more stable?
How is apparent brightness calculated?
How is apparent brightness calculated? Apparent brightness is thus measured in watts per square meter. For instance, the apparent brightness of the Sun is b = 1370 watts/meter2. That is, if you had a perfectly efficient solar panel one meter on a side, if you held it perpendicular to the Sun’s rays, it would generate […]
