Answer:
0.146 m
Explanation:
f = -KΔL according to Hooke's law
volume of water displaced = mass / density of block since a body will displace equal volume of its own
weight of water displaced = mass of water × acceleration due to gravity
and mass of water = volume of water / density of water
weight of water displaced = Vw × dw × g = mg (dw / dblock)
net force = mg - mg (dw / dblock) = 42.728 - 65.74 = -23.00
it will be balanced by a restoring force of 23 N
ΔL = F / k = 23 / 158 = 0.146 m
Answer:
v after 5s = 0.25 m/s, it took 10s to stop, it has traveled 2.5m before stopping
Explanation
We can use the equation of motion with constant acceleration
Given: v0= 0.5 m/s a= -0.05 m/s²
v(5s) = v0 + a×t = 0.25 m/s
Stop => v=0 => v0 + a×t = 0 => t=10s
Distance at t=10s ⇒ x(10) = 0.5×10 + 0.5x(-0.05)x10² = 2.5m
Answer:
W = Fd = KE =1/2mv²
Explanation:
not sure if that's what your looking for but i'm pretty sure this is it.
Determine the frequency and the speed of these waves. The wavelength is 8.6 meters and the period is 6.2 seconds. Now find speed using the v = f. λ equation<span>.</span>
<span>Electric field repulsive for objects of like charge and attractive for opposite type of charges and for a magnet you can say that like poles repel and unlike attracts so D makes sense</span>
