Thermal energy is transferred by $\sf\purple{conduction}$ when objects touch.

3. Conduction ✔

<h3>......................................................</h3><h2><u>MORE</u>:-</h2>

The heat transfer that occurs between two objects when they touch each other is called $\sf\pink{conduction}$ .
Heat is always transferred from the object at the higher temperature to the object with the lower temperature.

A baseball is hit from a height of 4 feet above the ground with an initial velocity of 110 feet per second and at an angle of 35

mrs_skeptik [129]

Answer:

Part a)

$h = 62.2 ft$

Part b)

It will not able to cross the pole

Explanation:

As we know that ball is hit with speed of 110 ft/s at an angle of 35 degree

so here we will say

$v_y = 110 sin35$

$v_x = 110 cos35$

now at the maximum height the vertical velocity will become zero

so here we can use kinematics

$v_f^2 - v_y^2 = 2 a h$

here we have

$a = -32 ft/s^2$

$v_f = 0$

$v_y = 63.1 ft/s$

now we have

$0 - 63.1^2 = 2(-32)h$

$h = 62.2 ft$

Part b)

now the height of ball is related to the distance from point of projection is given as

$y = xtan\theta - \frac{gx^2}{2v^2cos^2\theta}$

now we know that

$x = 375 ft$

$y = 375(tan35) - \frac{(32)(375^2)}{2(110^2)(cos35)^2}$

$y = 262.6 - 277.12 = -14.5 ft$

since its coming negative so it will not able to cross the pole

A capacitor of 30.0 μ F 30.0 μF and a resistor of 110 Ω 110 Ω are quickly connected in series to a battery of 4.00 V. 4.00 V. Wh

Tanzania [10]

Answer: $Q=31.368\ \mu C$

Explanation:

Given

capacitance $C=30\ muF$

Resistance $R=110\ Omega$

Applied Voltage $V=4\ V$

$t=0.001\ s$

Charge on Capacitor in a R-C circuit is given by

$Q=Q_0(1-e^{\frac{-t}{RC}})$

$Q=CV(1-e^{\frac{-t}{RC}})$

$Q=30\times 10^{-6}\times 4(1-e^{\frac{-0.001}{110\times 30\times 10^{-6}}})$

$Q=120\times 10^{-6}\times 0.2614$

$Q=31.368\ \mu C$
