Answer:

Explanation:

which is the heat capacity per unit mass of a material. Experiments show that the transferred heat depends on three factors: (1) The change in temperature, (2) the mass of the system, and (3) the substance and phase of the substance.

gogolik [260]

Thomson experiment he calculated the charge to mass ratio just be passing the fundamental charge through a tube

He calculated the charge to mass ratio just by finding the deflection of charge while it is passing through the constant electric field

so here we will use the deflection as following

let say it passes the field of length "L"

so here we have

$t = \frac{L}{v}$

now in the same time if it deflect by some distance

$\delta y = \frac{1}{2}at^2$

$\delta y = \frac{1}{2}{eE}{m}t^2$

now by solving this equation we can find e/m ratio

so here correct answer will be

the electron's charge-to-mass ratio

Answer

According the conservation of energy

$\dfrac{1}{2}mv_i^2+\dfrac{1}{2}I\omega_i^2+0 = mgh + 0$

I for ball = $\dfrac{2}{3}mr^2$

$\dfrac{1}{2}mv_i^2+\dfrac{1}{2} \dfrac{2}{3}mr^2\omega_i^2= mgh$

$\omega_i = \dfrac{v_i}{r}$

$v_i^2+\dfrac{2}{3}r^2(\dfrac{v_i}{r})^2 = 2gh$

$v_i^2+\dfrac{2}{3}v_i^2 = 2gh$

$v_i^2+[1+\dfrac{2}{3}]=2gh$

$v_i^2\dfrac{5}{3}=2gh$

$v_i=\sqrt{\dfrac{6gh}{5}}=\sqrt{\dfrac{6\times 9.8\times 5}{5}}$

$v_i = 7.67\ m/s$

a) $\omega_i = \dfrac{v_i}{R}$

$\omega_i = \dfrac{7.67}{0.113}$

$\omega_i =67.87\ rad/s$

b) $K_{rot} = \dfrac{1}{2}\dfrac{2}{3}mR^2\omega_i^2$

$K_{rot} = \dfrac{1}{3}\times 0.426\times 0.112^2\times 67.87^2$

$K_{rot} = 8.205\ J$

Earth’s crust continuously melts and solidifies in the upper mantle. Why does oceanic crust solidify faster than continental cru

Softa [21]

The oceanic crust solidifies faster than the continental crust. Because when magma comes into contact with ocean water it cools faster than when it reaches continental rock. Option C is correct.

<h3>What is the crust?</h3>

The outermost layer of a terrestrial planet is referred to as its "crust."

In the upper mantle, the Earth's crust is constantly melting and solidifying. Compared to magma beneath the continental crust, the oceanic crust has a lower temperature.

Magma cools more quickly when it comes into touch with ocean water than when it hits continental rock. causes the continental crust to solidify more slowly than the oceanic crust.

Hence option C is correct.

To learn more about the crust refer;
