In general if an object of mass M is placed on a plane inclined at an angle @, then Mg cos@ will be the reaction R and Mgsin@ will be the pulling force acting along the plane.
As it just starts moving at 25 deg, then the frictional force will be 3*9.8*sin25
ie 12.43 N
This may appear so from a Solar System perspective. The degrees of inclination range from 3.38 degrees for Mercury to Earth (which has the largest) with 7.55 degrees of inclination from the Sun's equator.
Hold a ruler level, then slope the ruler to an angle of 45 degrees. The inclination of the ruler is now 45 degrees. So if rock has been altered as to be unlevel, then the angle from the level is the rock beds inclination.
4*sin(10) = 0.6945927107 or about 0.7 km
The answer is 315 degrees!
Generally, that would be a protractor. It is able to take an angle and calculate its degrees.
The orbital inclination of the planet Neptune is 1.77 degrees. In comparison, the orbital inclination of the earth is 23.5 degrees.
Mercury, with an inclination of 7 degrees.
It is 0.01 degrees.
2.5 degrees.
== == Yes, it would mean that. But that is a rather extreme inclination. We're fortunate that it is in fact about 23.5 degrees.
This may appear so from a Solar System perspective. The degrees of inclination range from 3.38 degrees for Mercury to Earth (which has the largest) with 7.55 degrees of inclination from the Sun's equator.
23.5 degrees
The Earth's tilt, or inclination, or obliquity is about 23.44 degrees from the plane of its orbit around the Sun.
Boiler drum inclination is kept at 1:50 with the horizontal i.e. around 6 to 8 degrees.
Mercury is inclined at 7.0050.
its 66.5 degrees
Hold a ruler level, then slope the ruler to an angle of 45 degrees. The inclination of the ruler is now 45 degrees. So if rock has been altered as to be unlevel, then the angle from the level is the rock beds inclination.
