Answer:
h = 2.15 m
Explanation:
We can use the third equation of motion here to find out the height from which the cat fell that is the height of the refrigerator.
where,
g = acceleration due to gravity = 9.81 m/s²
h = height of refrigerator = ?
vf = final speed of cat = 6.5 m/s
vi = initial speedof cat vertically = 0 m/s
Therefore,
<u>h = 2.15 m</u>
Answer:
The maximum magnetic field strength is 833.33 T
Explanation:
The maximum magnetic field strength is equal:
Where
E = electric field strength = 2.5x10¹¹V/m
c = speed of the light = 3x10⁸m/s
Replacing:
I think the correct answers from the choices listed above are options A, E, and F. The conditions on <span>meteorites in space that are similar to those that likely prevailed on Earth early in its history would be </span>no oxygen, presence of inorganic molecules and <span>high levels of ultraviolet radiation. Hope this answers the question.</span>
Answer:
The bulk modulus of the liquid is 1.229 x 10¹⁰ Pa
Explanation:
Given;
density of liquid, ρ = 1400 kg/m³
frequency of the wave, f = 390 Hz
wavelength, λ = 7.60 m
The speed of the sound is given by;
v = fλ
v = 390 x 7.6
v = 2964 m/s
The bulk modulus of the liquid is given by;
where;
B is bulk modulus
B = (1400)(2964)²
B = 1.229 x 10¹⁰ N/m²
B = 1.229 x 10¹⁰ Pa
Therefore, the bulk modulus of the liquid is 1.229 x 10¹⁰ Pa
