What direct current in A will produce the same amount of thermal energy, in a particular resistor, as an alternating current tha

vodomira [7]

Answer:

$I_{rms}= 4.314 AExplanation:According to the definition of the root mean square value of current, the value of direct current which passes through the same circuit in which an alternating current is passing and producing same amount of heat as the direct current produced is called root mean square value of current. So, the relation between the root mean square value of current and the peak value of alternating current is given by [tex]I_{rms}=\frac{I_{0}}{\sqrt{2}}$

$I_{rms}=\frac{6.1}}{\sqrt{2}}$

[tex]I_{rms}= 4.314 A

Help asap!! The resultant force on the box is

rodikova [14]

The resultant force on the box is C) 10 Newtons to the left.

Explanation:

The figure of the problem is attached.

We see that there are two forces acting on the box along the horizontal direction:

- A force of 10 N acting to the right

- A force of 20 N acting to the left

By taking "to the right" as positive direction, we can rewrite the two forces as follows:

$F_1 = +10 N\\F_2 = -20 N$

Where the second force is negative since it acts to the left.

Since the two forces are in line, we can find their resultant simply by calculating their algebraic sum. By doing so, we find:

$F=F_1 + F_2 = +10 + (-20) = -10 N$

And the negative sign tells us that the direction is to the left.

Therefore, the correct answer is

C) 10 Newtons to the left.

A 0.600 m long pendulum is used to determine the acceleration due to gravity on a distant planet. If 20 complete oscillation are

givi [52]

Answer :

Explanation :

It is given that,

length of pendulum, l = 0.6 m

Number of oscillation, n = 20

time, t = 35.5 seconds

so, Time period, $T=\dfrac{t}{n}$
