When the power in their house unexpectedly went off, Radhika's mother said that she would check and replace the fuse. What exact
denis23 [38]

A) a piece of wire

Explanation:

Radhika's mother is simply replacing piece of wire.

A fuse is made up of a thin strip of wire that melts when there is an over current.

  • A fuse is electrical safety device in circuit that protects appliances from over current.
  • The wire in a fuse has a high resistance and low melting point.
  • When current is high, the resistance of the wire causes it to melt and break the circuit.
  • In this way, appliances are protected from the harmful effect of the surge in voltage.

A careful photographic survey of Jupiter's moon Io by the spacecraft Voyager 1 showed active volcanoes spewing liquid sulfur to
Over [174]

The concept used to solve this problem is that given in the kinematic equations of motion. From theory we know that the change in velocities of a body is equivalent to twice the distance traveled by acceleration, in other words:

v_f^2-v_i^2 = 2ax

Where,

v_{f,i} = Final and initial velocity

a = Acceleration

x = Displacement

For the given case, the displacement is equivalent to the height (x = h) and the acceleration is the same gravitational acceleration (a = g). In turn we do not have initial speed therefore

v_f^2 = 2hg

v_f = \sqrt{2hg}

Our values are given as

h = 70km = 70*10^3m

g = 2m/s^2

Replacing we have that,

v_f = \sqrt{2hg}

v_f = \sqrt{2(70*10^3)(2)}

v_f = 529.15m/s

Therefore the speed with which the liquid sulfur left the volcano is 529.15m/s

How much force is needed to accelerate a 1,100 kg car at a rate of 1.5 m/s2?
Anna [14]
Assuming there is no force of friction...

F = ma
F = (1300kg)(1.5m/s^2)
F = 1950N
Just multiply mass by acceleration.
1300 x 1.5 = 1950N.
