pretty sure thats my explanation "pretty sure" like my confidence? mark me brainliest bad at spelling lol
Answer:
ice
Explanation:
If the toy car is on a smooth surface, there is less friction. Therefore, the car will most likely go faster. Ice has the least friction so the toy car would travel fast.
Answer:
f = 0.4 Hz
Explanation:
The frequency of rotation of an object in order to achieve required centripetal or radial acceleration, can be found out by using the following formula:
f = (1/2π)√(ac/r)
where,
f = frequency of rotation = ?
ac = radial acceleration = 34.1 m/s²
r = radius = length of beam = 5.55 m
Therefore,
f = (1/2π)√[(34.1 m/s²)/(5.55 m)]
<u>f = 0.4 Hz</u>
This question is poorly stated, but I assume you mean what conditions are needed. It would have to be cold outside, correct?
Answer:
Thermal conduction is the transfer of internal energy by microscopic collisions of particles and movement of electrons within a body. The colliding particles, which include molecules, atoms and electrons, transfer disorganized microscopic kinetic and potential energy, jointly known as internal energy.
I believe it's conduction
