We know that 1 minute= 60 seconds (or 1 min= 60 s).
10 min* (60 s/ 1 min)* (2.0 m/ 1 s)= 1,200 m.
(Note that the units cancel out so you get the answer)
The final answer is 1,200 m.

The water. Take the specific heat of steel, estimate the volume of the nail, you know the volume of the water, which has a specific heat of one. Or be obvious. If you dropped a red hot nail into a liter of cold water, what would happen?
Answer:
Water
Helium atom, in other words, it consistis of a particle having four protons and two neutrons.
There are four (4) kinematic equations, which relate to displacement, D, velocity, v, time, t, and acceleration, a. Kinematic Equations Formula Questions
v=v0+at. v = v 0 + at.
d=12(v0+v)t d = 1 2 ( v 0 + v ) t or alternatively vaverage=dt. v average = d t.
d=v0t+(at22)
v2=v20+2ad.

Answer: B
F = 2.4 N
Explanation: Given that
Magnetic field B = 0.60 T
Current I = 5 A
Length L = 0.8 m
The force on an individual charge moving at the drift velocity Vd is given by F = qVdB sin θ.
Since current = charge/time
I = q/t
q = It
Also, recall that V = L/t. Therefore
F = I × t × L/t × B × sinØ
F = ILBsin θ
Since the wire is at right angles to the magnetic field
Sin θ = sin 90 = 1 then,
F = 5 × 0.8 × 0.6 = 2.4N
The force on the wire is 2.4 N
