Who discovered the surface of venus was noxious and hot?.
The discovery that the surface of Venus is noxious and hot can be attributed to several space missions and scientific observations. However, the first confirmation of Venus's harsh conditions came from the Soviet Venera 4 mission in 1967.
Venera 4, an unmanned spacecraft, successfully descended through Venus's atmosphere and transmitted data back to Earth. The mission's instruments indicated extreme temperatures, atmospheric pressure, and the presence of noxious gases, including sulfuric acid clouds.
This groundbreaking mission provided the initial evidence that Venus has a hostile environment with a thick, toxic atmosphere and intense heat.
Therefore, it was the Soviet Venera 4 mission that played a pivotal role in confirming the noxious and hot nature of Venus's surface.

A person is attracted towards the center of Earth by a 440 N gravitational force. The force with which Earth is attracted toward the person is _____.
A person is attracted towards the center of Earth by a 440 N gravitational force. The force with which Earth is attracted toward the person is 440 N.
Reason: If you were to consider Newton's third law, it says for every action, there is an equal and opposite reaction. That means if the earth exerts a 440N force on the human, then the human will exert a 440N force on the planet.
p.s. Newton's three laws would be very helpful to know for these sorts of conceptual questions that involve forces

What must be the acceleration of a box that is pushed with 86 N of force and experiences 29 N of friction? The mass of the box is 5 kg.
Answer:
In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities (in that they have magnitude and direction). The orientation of an object's acceleration is given by the orientation of the net force acting on that object. The magnitude of an object's acceleration, as described by Newton's Second Law, is the combined effect of two causes: the net balance of all external forces acting onto that object — magnitude is directly proportional to this net resulting force; that object's mass, depending on the materials out of which it is made — magnitude is inversely proportional to the object's mass.

What is the formula for principle of moments ?
Answer:
The Principle of Moments states that when a body is balanced, the total clockwise moment about a point equals the total anticlockwise moment about the same point. Moment =force F x perpendicular distance from the pivot d.
Why do perpendicular forces do No work?
Answer:
The definition of work is:
Force (dot product) distance = work
The dot product of vectors at right angles is zero - so no work can be done if the applied force is at a right angles to direction of motion
