Answer:
2084 kg*m/s
Explanation:
Impulse is change in momentum
Mathematically;
Impulse, J= F*t=mΔv where
F= ma = 1500 * { 30.56 - 16.67}/2*60
F= 1500 *0.11575
F= 174 N
J=F*t
J= 174*120*0.1
J= 2084 kg*m/s
Answer:
it is the bottom one
Explanation:
the wavelength is shorter but more compressed.
Child support is a term that refers to the obligation of a child's parents to provide economic support to the child even if the marriage between parents is over. That is, Child support states that even if they are no longer together as a family, parents of a child should take responsibility and provide practical support to the child, such as providing transportation, supplies or helping a baby economically.
Answer:
Explanation:
The beam of positively charged particles would not be deflected if the electric force acting on them is equal to the magnetic force:
where
q is the charge of the particles
E is the magnitude of the electric field
v is the speed of the particles
B is the intensity of the magnetic field
is the angle between the direction of v and B
Since the beam of particles travels perpendicular to the magnetic field, we have 
. So, we can rewrite the equation as
where
Substituting into the formula,
Answer:
its x and y component is 24.749m/s
Explanation:
Given
Speed of the dog = 35m/s
x component of the speed = xcos theta
y component of the speed = ycos theta
Given theta =45 degrees
x-component = 35cos45
x-component = 35(0.7071)
x-component = 24.749m/s
y-component = 35sin45
y-component = 35(0.7071)
y-component = 24.749m/s
Hence its x and y component is 24.749m/s
