Answer:
1.26 m/s²
Explanation:
Given:
Δx = 172 m
v₀ = 17.3 m/s
v = 27.1 m/s
Find: a
v² = v₀² + 2aΔx
(27.1 m/s)² = (17.3 m/s)² + 2a (172 m)
a = 1.26 m/s²
C. The heating element on a stove turning from black to orange
Hope this helps =]
Quantity of charge unloaded = 51.9 Coulombs
Potential difference = 10.93 megavolts = 1.093 x 10⁷ volts
1 volt = 1 joule per coulomb
1.093 x 10⁷ volts = 1.093 x 10⁷ joules per coulomb
Energy = (1.093 x 10⁷ J/C) x (51.9 C)
Energy = 567.267 megaJoules
That's <em>5.67 x 10⁸ Joules</em> .
==> My wife's blow-dryer is marked 1260 watts.
If the energy in this lightning strike could be collected, bottled, stored, and used as needed, it could run my wife's blow-dryer for 125 hours. That would save us more than $30 on our electric bill !
The correct answer is
(1) a 15-kg mass traveling at 5.0 m/s
<span>In fact, the inertia of an object depends only on its mass. The inertia gives a measure of "how hard is to put an object in motion", or "how hard is to stop an object in motion": the greater the mass, the larger the inertia of the object. In this problem, we have 4 objects, and the object with greatest mass is the first one (15 kg), therefore this is also the object with greatest inertia.</span>
