Answer:
19.5324 MPa
Explanation:
Information provided
Angle between the normal to the slip plane with tensile axis, 
Angle by slip direction with tensile axis,
Critical resolved shear stress,
Applied stress
Shear stress at slip plane
hence crystal won’t yield
Applied stress,
for crystal to yield is given by

Answer:
The time taken for the paint ball to hit the ground is 
The distance of the landing point from the tower is
Explanation:
From the question we are told that
The height of the tower is 
The speed of the paintball in the horizontal direction is 
Generally from kinematic equation we have that

Here u is the initial velocity of the paintball in the vertical direction and the value is 0 m/s , this because the ball was fired horizontally
a is equivalent to 
t is the time taken for the paintball to hit the ground
So

=> 
Generally the distance of its landing position from the tower is

=> 
=>
Answer:
Explanation:
Capacitance of the capacitor
C = ε₀ A / d
(8.85 x 10⁻¹² x .25² x 10⁻⁴) / 1 x 10⁻³
C = .553125 x 10⁻¹³ F
Charge = capacitance x volt
= .553125 x 10⁻¹³ x 1.5
= .8296875 x 10⁻¹³ C
no of electrons
= charge / charge on one electron
= .8296875 10⁻¹³/ 1.6 x 10⁻¹⁹
= 5.2 x 10^5
Answer:
-1.7534 Kg.m/s
Explanation:
Momentum, p is a product of mass and velocity, expressed as p= mv where m is the mass and v is the velocity which is dependent on the direction. Taking left as negative and right as positive then the initial momentum will be
p=-2.42*3.92+(3.7*2.09)=-1.7534 Kg.m/s
