the force is given by the equation

q*v*B [email protected]

thus it will be

(1.6*10^-19)*(7.8*10^4)*(3)*1/√2 which gives 2.6*10^-14 N

Formula

F = q*v*B Sin (theta)

Givens

q = 1.6*10^-19 coulombs

v = 7.8*10^4 m/s

B = 3 Tesla

phi = 45 degrees.

Solution

F = q*v*B * sin(45)

F = 1.6*10^-19 * 7.8*10^4 * 3 * Sin(45)

F = 2.6 * 10 ^-14

D

A catapult can project a projectile at a speed as high as 37.0 m/s. (a) if air resistance can be ignored, how high (in m) would
motikmotik

Then the maximum height of the catapult will be 69.78 meters.

<h3>What is kinematics?</h3>

The study of motion without considering the mass and the cause of the motion. The equation of motion is given below.

v = u + at

s = ut + (1/2)at²

v² = u² + 2as

A catapult can project a projectile at a speed as high as 37.0 m/s. (a) if air resistance can be ignored.

a = - 9.81 m/s²

u = 37 m/s

v = 0

s = h

Then the maximum height of the catapult will be given by the third equation.

v² = u² + 2as

0² = 37² - 2 × 9.81 × h

h = 37² / (2 × 9.81)

h = 69.78 meters

Then the maximum height of the catapult will be 69.78 meters.

More about the kinematics link is given below.

The first thing that made Trestail curious about the Crippen case was that __________.
Anna35 [415]
Possibly the third one down. I don't think that DNA was around in Crippen's time. I'm not a criminologist or associated fun and games, though.

a mango drops to the ground from the top of a tree which is 5 meter high,how does it take the mango to reach the ground​
tatuchka [14]

Gravity tends to pull the object towards the earth's surface, resulting in a drop or a free fall. Fruits falling from a tree, a stone thrown off a cliff, skydiving, and other free-fall motions are examples.

Mango takes 1.009 seconds to reach the ground.

<h3>What is free fall ?</h3>
  • A situation in which an object moves solely under the influence of gravity is referred to as free fall. An external force acts on the ball, causing it to move faster. This free fall acceleration is also known as gravitational acceleration. The term "free fall" refers to a downward movement with no initial force or velocity.
  • Gravity tends to pull the object towards the earth's surface, resulting in a drop or a free fall. Fruits falling from a tree, a stone thrown off a cliff, skydiving, and other free-fall motions are examples.

h = \frac{g t^2}{2}

where,

h = height = 5m ,

t = time ,

g =gravity = 9.8 m/s.

t^{2} = 2h / g = 10/9.8 = 1.02

t= \sqrt{1.02} = 1.009 sec
