An object having a mass of 11.0 g and a charge of 8.00 ✕ 10-5 C is placed in an electric field E with Ex = 5.70 ✕ 103 N/C, Ey =

Answer : $F_{x} = 45.6\times10^{-2}\ N$ , $F_{y} = 3040\times10^{-5} N$ and $F_{z} = 0\ N$

Explanation :

Given that,

Charge of the object q = $8.00\times 10^{-5}\ C$

Electric field in x-direction $E_{x} = 5.70\times10^{3}\ N/C$

Electric field in y- direction $E_{y} = 380\ N/C$

Electric field in z - direction $E_{z} = 0$

Now, using formula

$F = q E$

Now, the force on the object in x- direction

$F_{x} = 8.00\times10^{-5} C \times5.70\times10^{3} N/C$

$F_{x} = 45.6\times10^{-2}\ N$

The force on the object in y- direction

$F_{y} = 8.00\times10^{-5}\ C\times 380\ N/C$

$F_{y} = 3040\times10^{-5} N$

The force on the object in z- direction

$F_{z} = 8.00\times10^{-5}\ C\times 0$

$F_{z} = 0\ N$

Hence, this is the required solution.

The equation T^2=A^3 shows the relationship between a planet’s orbital period, T, and the planet’s mean distance from the sun, A

kobusy [5.1K]

Answer:

D. 2^(3/2)

Explanation:

Given that

T² = A³

Let the mean distance between the sun and planet Y be x

Therefore,

T(Y)² = x³

T(Y) = x^(3/2)

Let the mean distance between the sun and planet X be x/2

Therefore,

T(Y)² = (x/2)³

T(Y) = (x/2)^(3/2)

The factor of increase from planet X to planet Y is:

T(Y) / T(X) = x^(3/2) / (x/2)^(3/2)

T(Y) / T(X) = (2)^(3/2)

Compared to a soft sound, a loud sound at the same pitch....(check all true statements)

Sladkaya [172]

Answer:

One might think of a plucked guitar string - the sound would depend on the original amplitude of the disturbance -

Speed and velocity would still be the same

(b) is correct because the energy transfer depends on the original energy applied.
