<span>A mountain top has very high altitude, but valley has very low altitude comparing to a mountain.
As we go high temperature decreases accordingly .That is 1.8 F decreases in 165 feet.
As mountain are very high , so their temperature are very less comparing to a valley.</span>
Cell membrane. This is where chemicals enter and exit the cell.
Answer:
A) ΔV = 1.237 V
B) K.E = 1.237 eV
Explanation:
B)
The initial kinetic energy of the electron is given by the following formula:
where,
K.E = Kinetic Energy of electron = ?
m = mass of elctron = 9.1 x 10⁻³¹ kg
v = speed of electron = 660000 m/s
Therefore,
K.E = 1.98 x 10⁻¹⁹ J
K.E = (1.98 x 10⁻¹⁹ J)()
<u>K.E = 1.237 eV</u>
A)
The energy applied by the potential difference must be equal to the kinetic energy of the electron, in order to stop it:
where,
e = charge on electron = 1.6 x 10⁻¹⁹ C
Therefore,
<u>ΔV = 1.237 V</u>
Answer:
Los datos que tienes son:
m = 13 kg
d = 46 m
∪ = 0,45
g = 9,8 m/s²
Fr = ?
w = ?
Lo primero que haremos que calcular Fr
Fr = ∪mg
Fr = (0,45) (13 kg) (9,8 m/s²)
Fr = 57,33 N
Calculamos el trabajo realizado.
w = Fd
w = (57,33 N) (46 m)
w = 2637,18 Joules
Respuesta.
El trabajo realizado es 2637,18 Joules
