We will use formula for the orbital velocity of Venus, which is v = 35.02 km/s.
An average distance to the Sun ( In kilometers ) is:
R = 0.723 * 149,579,871 km= 108,150,260 km.
Than we will calculate the orbital period ( T ).
v = 2 π R / T
T = 2 π R / v
T = 2 * 3.14 * 108,150,260 km / 126,072 km/s
T = 5389.75 s ≈ 224.5 days
The orbital period of Venus is approximately 224.5 days.
Given the measured value of mass M in the experiment the error in 2M is ; dM
<u>Given data :</u>
Measured value of mass M = ( 0.743 ± 0.005 ) kg
<h3>The error in 2M in the measured value </h3>
The error in 2M in the measured value M = 0.743 ± 0.005 kg is dM while the error in M² will be 2dM
Hence we can conclude that the measured value of mass M in the experiment the error in 2M is ; dM.

Answer: If a velocity time graph is horizontal then the velocity is constant and there is no acceleration.
Answer:
Explanation:
Given:
Length of a rope,
Position of Canary on the rope from one end,
Position of Grackle on the rope from another end,
Tension in the rope,
linear mass distribution on the rope,
We have for the speed of wave on the string:
<em>For canary to be undisturbed we need a node at this location.</em>
<em>Also, at the end close to Canary there must be a node to avoid any change in pattern of vibration.</em>
So,
the distance between Canary and the closer end must be equal to half the wavelength.
∴Wavelength of wave to be produced = 20 m. This will give us nodes at the multiples of 10 and anti-nodes at the multiples of 5.
Now, frequency:
Answer: A.
series or parallel
Explanation:
Total resistance across any branch of a circuit can be found by analyzing whether the branch is connected in series or parallel.
The resistors are connected either in series or parallel. Therefore, the resistance of resistors across a circle can be calculated in series and parallel.
