Answer:
Explanation:
A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. ... Therefore, the oscillating material does not move far from its initial equilibrium position. Mechanical waves transport energy. This energy propagates in the same direction as the wave.
Answer:
1
Explanation:
Its 1 since the shape of it is more downwards which results the reflection going downwards.
Answer:
Adding a reducing agent
Explanation:
Homodimeric proteins are formed by non-covalent interactions between two identical proteins (monomers).
Some of these intermolecular interactions are mediated by disulphide bonds which can be broken by a reducing agent like beta-mercaptoethanol (2-ME).
By adding the reducing agent to the gel, it is probable that the dimer is broken and the band observed will correspond to the two identical 22.5-kDa monomers.
Answer:
3420.39 N
Explanation:
Applying,
Fd = 1/2(mv²-mu²)................. Equation 1
Where F = force on the bumber, d = distance, m = mass of the car, v = final velocity, u = initial velocity.
make F the subject of the equation
F = (mv²-mu²)/2d............... Equation 2
From the question,
Given: m = 890 kg, v = 0 m/s (to rest), u = 1.4 m/s, d = 0.255 m
Substitute these values into equation 2
F = [(890×0²)-(890×1.4²)]/(2×0.255)
F = -1744.4/0.51
F = -3420.39 N
The negative sign denotes that the force in opposite direction to the motion of the car.
