Answer:
equal
Explanation:
If all three corresponding sides are equal and all three corresponding angles are identical in measure, two triangles are said to be congruent. These triangles can be slides, rotated, flipped and turned to be looked identical. If repositioned, they coincide with each other. The symbol of congruence is' ≅'.
<h3>Answer: <u><em>Kinetic energy is the energy of motion. This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed. That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four.</em></u></h3><h3><u><em /></u></h3><h2>Explanation: <u><em>Hope this helps</em></u></h2><h2><u><em /></u></h2>
Answer:
the velocity of the kid is 5.6 m/s
Explanation:
r is the radius and w is the frequency.
so we should know that the diameter is 18m and the diameter is equal to two times the radius, so r = 18m/2 = 9m
we should also know that the circumference of a circle is equal to c = 2pi*r, so each revolution has this length. if the kid does 5.9 revolutions in one minute then the kid spins at v = 5.9*2pi*9m/min
so we want to write this in meters per second and this means that we need to divide it by 60!
v = (5.9*2pi*9/60)m/s = 5.56 m/s
so your answer will be 5.6 m/s glad i could help!
Answer:
The displacement of the same mass on the same spring on the Moon is 0.05 m.
Explanation:
Given;
mass suspended from one end of the spring, m = 0.500 kg
displacement on the spring on Earth, x = 0.3 m
Apply Newton's second law of motion;
F = ma = mg
where;
m is mass on the spring
g is acceleration due to gravity
Also, apply Hook's law;
F = Kx
where;
K is force constant
x is extension or diplacement of the spring
Combine the two equations from the two laws;
mg = kx
when the spring in on Earth;
0.5 x 9.8 = 0.3k
4.9 = 0.3k
k = 4.9 / 0.3
k = 16.333 N/m
when the spring is on moon;
mg = kx
mass is the same = 0.5 kg
acceleration due to gravity on moon = ¹/₆ that of Earth = ¹/₆ x 9.8 m/s²
0.5 (¹/₆ x 9.8) = 16.333 x
0.8167 = 16.333 x
x = 0.8167 / 16.333
x = 0.05 m
Therefore, the displacement of the same mass on the same spring on the Moon is 0.05 m.
