Answer:
500 Ns
Explanation:
According to the impulse theorem, the change in momentum of an object is equal to the impulse exerted on it. Mathematically:
where
is the change in momentum of the object
I is the impulse exerted, which is the product of
F, the net force exerted
, the time interval during which the force is applied
In this problem,
F = 100 N is the force applied on the wagon
is the time interval
Substituting, we find the change in momentum of the wagon:
In a parallel circuit, both bulbs are connected directly to the power supply
or battery. As long as the power supply is capable of running both of them,
neither bulb is aware of the other's presence. If one bulb fails 'open', the
other bulb doesn't change at all. The voltage across it, the current through it,
its resistance, and its brightness,all remain exactly as they were before.
Answer:
Sound waves bend around the corners of various obstacles.
Explanation:
I took the test
Answer:
60 cycles
Explanation:
The first thing we must do to solve the problem is to find how many cycles are presented in 1cm by multiplying the frequency by the base time of the
K=time base=2ms/cm=2x10-3s/cm
f=frecuency=3000s^-1
N=fk
N=(3000)(2x10^-3)=6cycles/cm
Ntot=6x10=60cycles
False, fission is when an atom splits into two parts.
