Answer:
Time taken by the leaf to displace by 1.0 m distance is
seconds
Explanation:
As we know that initial velocity of the leaf is given as
now the acceleration upwards for the leaf is
The displacement of leaf in upward direction is
d = 1 m
so now we have
seconds
Photon
energy is the energy carried by a single photon with a certain wavelength and
frequency. These terms are related by an equation. <span>
E = hv
<span>where h is the Planck's constant (6.626 x
10-34 J s), v is the frequency which is related to the wavelength by:
λv = c where λ is the wavelength and c is the speed of light (3.00 x
108 m/s)
</span>
Therefore, the energy equation
<span>E = hc / λ
E = (6.626 x 10-34 J s)(3.00 x 10^8 m/s) / 0.0120 m = <span>1.657 x 10^-23 J</span></span></span>

Answer: *The inner planet that has two moons is Mars * the only planet in the Solar System with clockwise rotation is Venus * The surface of Mercury is covered with ancient magma ( which is similar to the spews of volcanoes on Earth as well) * The planet that is closest to Earth is Mercury * Venus has more volcanoes than any other planet * Earth's moon formed when a(n) can sometimes be called the Big Splash or can be called the Theia impact (Luna the moon formed from the ejecta of the collision between the Proto- Earth and Mars sized planet) * Mars is called the red planet because it's soil contains the element iron oxide ( which is the compound that gives blood and rust hue)

Answer: B = 1.69 T
Explanation: Given that the
Electron velocity V = 7.4 × 10^5 m/s
Force F = - 2 × 10^-13 N
Charge q = -1.602 x 10-19 C.
We are given the charge, its velocity, and the magnetic field strength and direction. We can thus use the equation F = qvB sin θ .
Since the electron is moving perpendicular to a magnetic field,
sin θ = sin 90 = 1, therefore
- 2 × 10^-13 = - 1.602×10^-19 × 7.4×10^5B
B = -2×10^-13/1.2×10^-13
B = 1.68708T
B = 1.69 T
