A 10kg block of wood is pulled across a level ground by fore of 15N applied at an angle of 30 degree from the horizontal. How much work is done, if it is moved to a distance of 3m?
If the block of wood is moved to a distance of 3 meters, the amount of work done is equal to 38.97 Joules.
What is work done?The work done (W) by an object can be calculated by multiplying the force acting on it by the perpendicular distance covered by the physical object. This ultimately implies that, work done (W) and energy (E) have the same unit i.e Joules (J).
Mathematically, the work done (W) by an object can be calculated by using this formula:
Work done (W) = force × distance
Work done (W) = mgdcosθ or Fdcosθ
Substituting the given parameters into the formula, we have;
Work done (W) = 15 × 3 × cos30
Work done (W) = 15 × 3 × 0.8860
Work done (W) = 38.97 Joules.

What phenomena causes stars and galaxies to appear red when they are moving away from us?
the Doppler effect
the radar effect
the red planet effect
the siren effect
The phenomenon that causes stars and galaxies to appear red when they are moving away from us is called "The Doppler Effect". (Option A)
How would one define the Doppler Effect?We've known that most other galaxies are moving away from us since 1929, when Edwin Hubble revealed that the Universe is expanding. Light from these galaxies is displaced to longer (and hence redder) wavelengths it is red when it is shifted.
The Doppler Effect is illustrated through redshift. As an item travels away from us, the sound or light waves it emits are stretched out, resulting in a lower pitch and a shift to the red end of the electromagnetic spectrum, where light has a longer wavelength.
