Answer:
The magnitude is 
The direction is the positive x axis
Explanation:
From the question we are told that
The electric field is E = 450 V/m in the negative y ‑direction
The speed of the proton is
in the positive z direction
Generally the overall force acting on the proton is mathematical represented as

Now for the beam of protons to continue un-deflected along its straight-line trajectory then 
So

=> 
Generally from unit vector cross product vector multiplication

So the direction of B (magnetic field must be in the positive x -axis )
So

=> 
=>
=>
=> 
=>
Explanation:
With most of our blue planet covered by water, it's little wonder that, centuries ago, the oceans were believed to hide mysterious creatures including sea serpents and mermaids. Merfolk (mermaids and mermen) are, of course, the marine version of half-human, half-animal legends that have captured human imagination for ages. One source, the "Arabian Nights," described mermaids as having "moon faces and hair like a woman's but their hands and feet were in their bellies and they had tails like fishes."
C.J.S. Thompson, a former curator at the Royal College of Surgeons of England, notes in his book "The Mystery and Lore of Monsters" that "Traditions concerning creatures half-human and half-fish in form have existed for thousands of years, and the Babylonian deity Era or Oannes, the Fish-god ... is usually depicted as having a bearded head with a crown and a body like a man, but from the waist downwards he has the shape of a fish." Greek mythology contains stories of the god Triton, the merman messenger of the sea, and several modern religions including Hinduism and Candomble (an Afro-Brazilian belief) worship mermaid goddesses to this day.
Answer:
The voltage is 2.114 V.
Explanation:
Given that,
Mass of both weights = 225 gm
Transducer sensitivity = 0.5 V/N
The first mass is located 20∘ north of east, the second mass is located 20∘ south of east,
We need to calculate the net equivalent force
Using formula of force


Put the value into the formula


We need to calculate the voltage
Using formula of voltage

Put the value into the formula


Hence, The voltage is 2.114 V.
As the plane falls the parabolic path remains directly below as the plane continues to fly over. This give more of an overview. When the package falls vertical acceleration happens as there is a vertical velocity as the package falls form high above. The downwards motion of gravity acts on the package if the approximated projectile motion ignoring air resistance.
Answer:
Calculate 'R' of convex mirror and height of the real image
the radius of the convex mirror is 48cm
Explanation:
Distance between convex and concave mirror is =60cm
Radius of the concave mirror (R) = 200cm
For the concave mirror, u = ∞
V = {R}/{2}=100cm
The object for the convex mirror and the final image is on the pole of the concave mirror, and distance between convex and concave mirror is 60cm
u_1=60-100 =-40cm
Object will be behind the convex mirror
1/f=1/40+1/60
f=24cms
the radius of the convex mirror is 48cm
