Answer:
Because the Earth has it's own gravity that keeps us put, and we also have the moon.
Explanation:
Answer:
changes electrical energy into mechanical energy
Answer:
2.94 x 10⁵ Pa
Explanation:
m = mass of the car supported by four ires = 1200 kg
g = acceleration due to gravity = 9.8 m/s²
A = Area of contact for each tire = 100 cm² = 100 x 10⁻⁴ m²
n = Number of tires
P = Gauge pressure
Using equilibrium of force in vertical direction
n P A = mg
4 P (100 x 10⁻⁴) = (1200) (9.8)
P = 2.94 x 10⁵ Pa
Answer:
The flux of the electric field through the surface is 3.24\times10^{3}\ Nm^/C[/tex].
Explanation:
Given that,
Area of cube = 48 cm²
Charge = 28.7 nC
We need to calculate the flux of the electric field through the surface
Using formula Gauss's law
The electric flux through any closed surface,
Where, q = charge
Put the value into the formula
Hence, The flux of the electric field through the surface is 3.24\times10^{3}\ Nm^/C[/tex].
<span>This problem asks that we compute the magnitude
of the maximum stress that exists at the tip of an internal crack
</span> sigmam=2*(sigma0)(a/(pt))^(1/2)
sigmam= 2*(180)*(((3.5×10^-2)/(2))/(4.5×10-4))^(1/2)=2245 MPA (325609.7 PSI)
