Density = (mass) / (volume)
4,000 kg/m³ = (mass) / (0.09 m³)
(4,000 kg/m³) x (0.09 m³) = mass
mass = 360 kg
force of gravity = (mass) x (acceleration of gravity) = (360 kg) x (9.8 m/s²) = (360 x 9.8) kg-m<span>/s² </span><span>= </span>3,528 newtons .
Answer:
<h2>
280.86 m</h2>
Explanation:
Range is defined as the distance covered in the horizontal direction. In projectile, range is expressed as x = vt where;
x is the range
v is the velocity of the runner
t is the time taken
Before we can get the range though, we need to find the time taken t using the relationship S = ut + 1/2gt²
if u = 0
S = 1/2gt²
2S = gt²
t² = 2S/g
t = √2S/g
t = √2(141)/9.8
t = √282/9.8
t = 5.36secs
The range x = 52.4*5.36
x =280.86 m
Hence, the coyort lies approximately 280.86 m from the base of the cliff
The density will always be the same.
<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>
