Answer:
Answer: C
explanation:
They could be same or different
ie:
|-5|,|-5| = 5,5
|-5|,|5| = 5,5
<span>Brownian
motion is the random movement of colloidal particles suspended in a fluid. It is
caused by random collisions of the molecules in the fluid medium. The particles
in the solution or colloids are in constant random movement. A colloid has
properties boundary to a homogenous and heterogeneous mixture. However in
Brownian movement, the larger the size of a particle, the lesser its motion and
the smaller the size of the particle, the higher is motion. Colloids in general
have larger particle size and therefore it Brownian motion is sluggish. The statement
is false.</span>
Explanation:
The wavelength, λ defined as the total distance traveled by the wave in one full cycle of motion. In other words, wavelength can be given by horizontal distance between repeating units of wave pattern.
Also, the wavelength of a transverse wave can be measured as the distance between two adjacent crests or troughs.
λ × f = v
Where,
f = frequency in Hz
v = speed in m/s
Car designers will more than likely go back to the lab and change certain aspects of the car (Thickness of body, design of the vehicle's frame, etc.), thus making it more durable.
Gravitational Potential Energy = mgh (m=mass; g=gravitational force(9.8N/kg); h = height)
Ug = (70kg)(9.8N/kg)(8m) = 5488J which is C.)
