Answer:
Zero
Explanation:
Impulse is defined as the change in momentum.
Impulse is also defined as the product of force and the time duration of application of the force.
In the given problem, since there is no motion in the vertical direction, therefore the velocity of the box along the vertical direction is zero. So, momentum of the box along the vertical is also zero.
Hence the change is momentum is also zero along vertical direction.
Thus the impulse delivered by the box is zero.
Explanation:
binary number is a number expressed in the base-2 numeral system or binary numeral system, which uses only two symbols: typically "0" and "1".
This one is complicated. Not hard, but several steps. The two 5-ohm resistors in series have a total resistance of 10 ohms. 1.6 A through 10 ohms means the battery is (1.6 x 10)=16 volts. Then ... 16 volts produces 2A of current through (16/2)=8 ohms of resistance. If 3 identical resistors in parallel look like like 8 ohms, then each one is (8 x 3)= 24 ohms. That's D.
Sound is all about vibrations.
The source of a sound vibrates, bumping into nearby air molecules which in turn bump into their neighbours, and so forth. This results in a wave of vibrations travelling through the air to the eardrum, which in turn also vibrates.
Answer:
True
Explanation:
Low melting points and lack of electrical conductivity ARE properties of molecular compounds.
