Answer:
7.4 x 10⁻⁵ T.
Explanation:
Emf induced = BLv
Where B is magnetic field , L is length of rod or any other object moving in magnetic field and v is velocity of moving rod.
Here B = 56 x 10⁻⁶ T
L = 88 X 10⁻² m
v = 1.5 m/s
emf induced = 56 x 10⁻⁶ x 88 x 10⁻² x 1.5
= 7.4 x 10⁻⁵ T.
Answer:
359 m/s
Explanation:
Highest frequency a person can hear is 20,000Hz.
f = c × λ
Frequency = Wave speed × Wavelength
Wavelength = 20,000 ÷ 343 = 58.31m
Wavespeed = Frequency ÷ Wavelength
c = 20,950 ÷ 58.31 = 359.3 m/s
= 359 m/s (3 s.f.)
Answer:
a = 15.1 g
Explanation:
The relation between mass and acceleration is given by :
If a₁ = 0.80g, m₁ = 1510 kg, m₂ = 80 kg, we need to find a₂
So,
So, the car's acceleration would be 15.1 g.
The acceleration of gravity on Jupiter is listed as <em>24.79 m/s²</em> .
That's roughly 2.53 times its value on Earth. So if you weigh, let's say,
130 pounds on Earth, then you would weigh about 328 pounds on Jupiter.
