Answer:

raise the board to a higher angle

Explanation:

Static friction is the force opposite to the applied force.

Static friction is dependent on the angle of inclination, it means as the angle of incline increases, the force of friction will increases as normal force will decrease.

So, if the board will be raised to a higher angle, it will increase the angle of incline and will overcome the static friction and block will be able slide.

Hence, the correct option is "raise the board to a higher angle".

A small 32-kilogram canoe broke free of its dock and is now floating downriver at a speed of 2.5 m/s. What is
marysya [2.9K]
<h3>Answer:</h3>

80 kgm/s

<h3>Explanation:</h3>

<u>We are given;</u>

  • Mass of the Canoe is 32 kg
  • Speed of the Canoe is 2.5 m/s

We are required to calculate the momentum of the Canoe?

  • We need to know that momentum is the product of mass of an object and its speed.
  • Therefore;

Momentum = Mass × speed

Therefore;

Momentum = 32 kg × 2.5 m/s

                   = 80 Kgm/s

Thus, the momentum of the Canoe is 80 kgm/s.

Which term describes the object that a satellite revolves around?
m_a_m_a [10]

The object that a satellite revolves around is the <em>central body</em> of the system. <em>(C)</em>

For example:

-- The central body of the solar system is the Sun.

-- The central body for TV satellites, GPS satellites, weather satellites, and the International Space Station is the Earth.

-- The central body for Phobos and Deimos is Mars.

This should be a pretty easy question to answer by elimination, when you notice that "Orbit", "Period", and "Rotation" are not "Bodies".
