90 degrees - 30 = 60 degrees
Velocity = (5m/s - 4.35m/s x cos(30)) / cos(60)
Velocity = 2.47 m/s
The answer is D) 2.47 m/s at 61.9 degrees
The Energy related to object motion.Potential energy most commonly refers to gravitational potential energy, which is energy associated with an object's elevation. For an object of mass m and elevation z, its potential energy is mgz where g is the gravitational constant .............. HOPE IT HELPS YOU :)
Answer: question 1 is b I believe
Explanation:
every action has an opposite reaction
<h2>
Answer: size</h2>
Gel electrophoresis is called to the technique used by scientists for analytical purposes, in life sciences laboratories to separate macromolecules (DNA, RNA, and proteins from various sources).
The process consists of separating the molecules according to their <u>size</u> and <u>electric charge</u>. This is done with a gel (a gelatinous substance extracted from seaweed, called <em>agarose</em>) of controllable porosity placed in an ionic buffer environment. This is how the gel acts as a molecular sieve that separates larger molecules from the smaller ones, because each molecule has different size and charge and will move through the gel at different speeds.
That is, the smaller molecules move more quickly through the gel while the larger ones are left behind.
Answer:
α = 
Explanation:
Applying the equations of motion to determine angular acceleration of the unit,
The sum of moments about O is equal to the product of angular acceleration and moment of inertia
∑Mo = Io*α
Taking the anticlockwise direction as positive moment,
= ( -(1150) + (1400) ) * (0.5 / 2) + ( (475) - (650) ) * (0.3 / 2) - F = Io*α
= 36.5 - (2.5 N.m) =
*α
NOTE: moment of inertia of the pulleys in this instance =
Hence, 33.75 = 
* α
Solving, α =
