Answer:
0.3 A
Explanation:
Build the circuit attached. Make sure the switch is turned off as you build the circuit. Set the Selected battery voltage to 10 volts.
A. Based on the number on the fuse, what do you think is the maximum current allowed in this circuit?
Solution:
A fuse is a safety device which is used in circuits for preventing very high currents which can cause overloading or start a fire. A fuse is made up of a low resistance thin piece of metal such that the flow of high current can cause the metal to melt leading to an open circuit. A fuse lets current flow up to a maximum value before it melts and the circuit will be broken.
From the image attached, since the maximum rating of the fuse is 0.3 A, hence the maximum current that can flow through the circuit is 0.3 A.
Answer:
Explanation:
Potential energy at the surface
= -GMm / R
= -6.6 x 10⁻¹¹ x 6 x 10²³ m / 3400 x 10³
= -1.1647 x 10⁷ m
If v be required velocity
Total energy at surface
= 1/2 m v² -1.1647 x 10⁷ m
= energy at farr off = 1/2 m x 3000²
1/2 m v² - -1.1647 x 10⁷ m = 1/2 m x 9 x 10⁶
1/2 v²= 1.1647 x 10⁷ + .45 x 10⁷
= 1.6147 x 10⁷
v² = 2.3303 x 10⁷
v = 4.827 x 10³ m / s
b ) For final speed zero at infinity
1/2 m v² - -1.1647 x 10⁷ m = 0
1/2 v² = 1.1647 x 10⁷
v² = 2.3294 x 10⁷
v = 4.826 x 10³ m /s
Increasing the mass attached to a spring will increase it's vibrational period - this is true. Imagine placing an elephant at the end of a bungee cord vs an apple, the apple will recoil faster than the elephant.
