Answer:
Hello! Your answer is, sound in the air is faster
Explanation:
The speed of sound through air is about 340 meters per second. It's faster through water and it's even faster through steel. Light will travel through a vacuum at 300 million meters per second. So they're totally different scales.
Hope I helped! Ask me anything if you have any questions! Brainiest plz. Hope you make an 100% and have a nice day! -Amelia♥
They cant occupy the same box in the periodic table because each atom has a certain number of protons which is the atomic number and no two atoms have the same amount of protons.
The resultant force on the system is equivalent to the difference in the weights of the chandelier and Robin Hood.
F(net) = 240g - 85g
F(net) = 155g
Robin Hood's Acceleration:
F = ma
155g = 85a
a = 17.89 m/s²
Tension = mg + ma
Tension = 85(g + a)
Tension = 2400 N
Answer:
h = 219.96 m
Explanation:
Speed of the stone with which it was thrown horizontally, v = 10 m/s
We need to find the height of the cliff if the stone’s trajectory time from the top of the hill to the bottom to be 6.7s.
It means we need to find the distance covered by the stone. As the horizontal speed of the stone is given , it means there is no vertical motion in the stone,u'=0
Using second equation of motion,
Put u'=0 and a=g
So,
So, the height of the cliff is 219.96 m.
Answer:
Towards left
Explanation:
Applying Fleming Right hand rule in which the middle finger denotes downward magnetic field. Thumb pointing towards you is the direction of motion of electron beam.The direction of force on the electron indicated by the index finger is towards left. Hence the electron beam is deflected towards left.
