Answer:
The horizontal component of the truck's velocity is: 23.70 m/s
The vertical component of the truck's velocity is: 3.13 m/s
Explanation:
You have to apply trigonometric identities for a right triangle (because the ramp can be seen as a right triangle where the speed is the hypotenuse), in order to obtain the components of the velocity vector.
The identities are:
Cosα= 
Senα= 
Where H is the hypotenuse, α is the angle, CA is the adjacent cathetus and CO is the opposite cathetus
The horizontal component of the truck's velocity is:
Let Vx represent it.
In this case, CA=Vx, H=24 and α=7.5 degrees
Vx=(24)Cos(7.5)
Vx=23.79 m/s
The vertical component of the truck's velocity is:
Let Vy represent it.
In this case, CO=Vy, H=24 and α=7.5 degrees
Vy=(24)Sen(7.5)
Vy=3.13 m/s
A light goes out when you turn off the wall switch because <u />B. the switch causes a break in the circuit.
Since there is a break in the circuit, electricity cannot come through to the bulb, which is why there is no light anymore.
The value of the underlined 8 is, hundred billion's. Hope this helped!
A concave lens can only form a virtual image. The correct option among all the options that are given in the question is the third option or option "C". Concave lenses are mostly thinner in the middle compared to its edges. I hope that this answer has come to your help.
Answer:
Only 2,3,4 are true
Explanation:
Bosons Particles are particles that condense to the same state. Bosons particle have integral spin like 0 , 
, 
, 
, etc. Bosons particles always have asymmetric wave function and there is exchange of particles.
1) It does not obey Fermi_ Dirac statistics
2) It obeys Bose-Einstein statistics
3) The object can have intrinsic spin
4) Yes the Bosons particle is always symmetric with exchange of particles
5) No Bosons particle are symmetric and not asymmetric
