Answer:
L = 3.35 m
Explanation:
given,
mass of the block = 0.2 Kg
spring constant = 1.40 kN/m
until spring compressed = 10 cm
inclination of ramp = 60°
now,
initial potential energy of spring = (work done by friction) + (final gravitational potential energy of block)
L = 3.35 m
Explanation:
the atom are comprised of particle. this atomic theory also proves that atoms cannot be destroyed nor created and it composed of many particles. it is also said that atoms of the same element can be identical.
Power = (work done) / (time to do the work)
Power = (2000 J) / (5 sec)
<em>Power = 400 watts</em>
Answer:
A) R = 1019.11 Ω
B) V = 101.91 V
Explanation:
a) The resistance is given by the formula;
R = ρL/A
Where;
ρ is bulk density = 5.0 Ωm
L is length of cylinder = 1.6m
A is area = (π/4)D² = (π/4) x 0.1² = 0.007854 m²
Plugging in the relevant values, we obtain ;
R = (5 Ωm x 1.6m)/(0.007854 m²)
R = 1019.11 Ω
b) potential difference is given by;
V = RI
Thus, plugging in relevant values, we obtain;
V = 1019.11 Ω ∙ 0.1A
V = 101.91 V
Explanation:
Cheetahs can go from 0 to 60 miles per hour in just 3.4 seconds and reach a top speed of 70 miles per hour. While they are the fastest land animal in the world, they can only maintain their speed for only 20 to 30 seconds.
