Answer:
The block will not move.
Explanation:
We'll begin by calculating the frictional force. This can be obtained as follow:
Coefficient of friction (µ) = 0.6
Mass of block (m) = 3 Kg
Acceleration due to gravity (g) = 10 m/s²
Normal reaction (R) = mg = 3 × 10 = 30 N
Frictional force (Fբ) =?
Fբ = µR
Fբ = 0.6 × 30
Fբ = 18 N
From the calculations made above, the frictional force of the block is 18 N. Since the frictional force (i.e 18 N) is bigger than the force applied (i.e 14 N), the block will not move.
Answer:
(1) Resonance
Explanation:
Resonance is the process whereby a system is set into vibration due to the vibration of a nearby system with larger amplitude. The frequency at which this vibration takes place is called the resonant frequency.
It is a phenomenon of amplification that occurs when the frequency of a periodically applied force is in harmonic proportion to the natural frequency of the system on which it acts.
inferior is an antonym of superior. Superior is an antonym of inferior.
As adjectives the difference between inferior and superior is that inferior is of lower quality while superior is higher in quality.
As nouns the difference between inferior and superior is that inferior is a person of lower stature to another while superior is a person of higher rank or quality.
'Greater' or 'smaller' means whatever the force is right now would change.
In order to figure out how it would change, we would need to know what
the cube is surrounded by right now, before it goes into the water.
What I'm really trying to say is: There's not enough information in
the question for us to be able to answer it.
Answer:
KE = 1/2 M v^2 kinetic energy of projectile
KE = 1/2 * 20 * (54 m/s)^2 = work done on projectile
W = 10 * 54^2 = work done on projectile
W = 29,160 J
