Answer:
Explanation:
Speed of van, v = 28 m/s
Radius of unbanked curve, r = 150 m
Let 
is the angle with the vertical. In case of banking of road,
.............(1)
And
..........(2)
From equation (1) and (2) :
So, the string makes an angle of 28.07 degrees with the vertical. Hence, this is the required solution.
N₂ / N₁ = 13.3
A transformer is a device that changes the voltage in the primary, causing a voltage to be induced in the secondary. The expression for this voltage ratio is
ΔV₂ = N₂ /N₁ ΔV₁
where N is the number of windings on each side and V2 and V1 are the voltages in the secondary and primary, respectively.
They state that the primary voltage in this instance is 9.0 V and the secondary voltage is 120 V.
ΔV₂ /ΔV₁ = N₂ / N₁
N₂ / N₁ = 120/9
N₂ / N₁ = 13.3

A 9.0-V battery (with nonzero resistance) and switch are connected in series across the primary coil of a transformer. The secondary coil is connected to a light bulb that operates on 120 V. Determine the ratio of the secondary to primary turns needed for the bell's transformer. Determine the ratio of the secondary to primary turns needed for the bells transformer. Ns/Np=?
The wavelength of a photon of electromagnetic radiation with a frequency of 151.7 Mhz is 1.978 meter
According to the question
The frequency of a photon of electromagnetic radiation = 151.7 Mhz
By using the Formula of wavelength and frequency
λ = C/f
Where,
λ (Lambda) = Wavelength in meters
C = Speed of Light (c = 3x10⁸ m/s)
f = Frequency
Now, the wavelength of a photon of electromagnetic radiation with a frequency of 151.7 Mhz is
1 Mhz = 1000000 Hz
151.7 Mhz = 151.7 * 10⁶ Hz
λ = C/f
Substituting the value of C and f
λ = 
λ = 1.978 meter
Hence, the wavelength of a photon of electromagnetic radiation with a frequency of 151.7 Mhz is 1.978 meter

Answer:
The two chairs and those sitting on them will move in nearly opposite directions at almost the same speed (assuming that the wheels can only move into two directions - front or back and assuming that the weight of both people are almost the same)
Explanation:
Newton's Third Law states that If an object X exerts a force on object Y, then object Y must exert a force of equal magnitude and opposite direction back on object X.
In other words, when force is applied from source A at B and in direction of B, B also simultaneously returns the force on B and in the direction of B.
This law applies when we jump off the ground when a rocket takes off from the earth into space, etc.
While standing, the body pushes on the earth with a force equal to its own weight. If the ground underneath the body does not meet that force in an equal and opposite direction, both standing on the earth will fall into the earth, with the earth caving underneath it.
You can see why it is important to have a strong foundation for a building and why the depth and strength of the foundation will depend on how much weight is going on it.

When an air bubble gets trapped inside the gas collection tube, then the gas that is actually collected becomes impure. This will definitely give an inaccurate result and the calculated percentage yield will be wrong. I hope that this is the answer that you were looking for and it has come to your help.
