Answer:
0.174413400763 s
Explanation:
L = Length of rod = 90 m
Speed of sound in air = 344 m/s
= Density of brass = 8600 kg/m³
Y = Young's modulus =
Velocity of sound in a material is given by
Time taken in brass
In air
The time interval is
Answer:
Because the rope is stopping the force of gravity from acceleration it.

Answer:
<h2>when metallic oxides react with water they form metallic hydroxides which are basic in nature.to show that these are basic in nature,we should conduct a litmus paper test.in this experiment,we will observe that red litmus turns blue on coming in contact with them. this shows that metallic oxides are basic in nature</h2>
The tension in the cable is equal to 323.5 N.
<h3>What is the tension in the cable?</h3>
The tension, T in the cable is determined by taking moments about the pivot marked X.
The angles of the boom and the cable with the horizontal are first calculated.
Angle of the boom with horizontal, θ = tan⁻¹(5/10) = 26.56°
The angle of cable with horizontal, B = tan⁻¹(4/10) = 21.80
Taking moments about the pivot:
175.5 * cos 26.56 + 94.7 * cos 26.56 * 0.5 = T (sin(26.56 + 21.80) * 1
Tension = 241.68/0.747
Tension = 323.5 N
In conclusion, the tension in the cable helps to suspend the crate.
