A box is at rest on an inclined surface. Which diagram correctly illustrates all forces, including any component forces? Assume
1 answer:
A box is at rest on an inclined surface. The last diagram correctly illustrates all forces, including any component force, therefore the correct option is D.
<h3>Describe friction?</h3>When two physical objects' surfaces come into contact, a force called friction acts to hinder or resist the relative motion of the items. Any two surfaces of things cannot simply slide over or across one another due to the friction force. It depends on the amount of force used on the object.
Additionally, there should be no net vertical forces acting on the inclined block. Fv=0
Therefore, the appropriate diagram is D.

Answer:
Explanation:
Given
Initial Velocity (u)=13 m/s
angle
distance between fence and deer=2.5 m
We consider deer jump similar to projectile motion
equation of trajectory
Thus deer will cross the fence with an difference in its jump and fence
1.5-1.148=0.351 m
so deer rises during when it is over fence
Answer:
correct option is a. 0.2 mA toward D
Explanation:
given data
B carries = 1.5 mA
C carries current = 1.3 mA
solution
we take positive direction of current going away from the point D
and negative direction of current coming towards point D
so we use here kirchoff's current law that is
iA + iB + iC = 0 ......................1
iA + 1.5 + (-1.3) = 0
iA = - 0.2 mA
so that current in wire A is 0.2 mA towards point D
correct option is a. 0.2 mA toward D
Answer:
a)
b)
c) Q = 1.256 × 10⁻³ m³/s
Explanation:
Given:
The velocity profile as:
Now, the maximum velocity of the flow is obtained at the center of the pipe
i.e r = 0
thus,
or
Now,
or
or
Now, the flow rate is given as:
Q = Area of cross-section of pipe ×
or
Q =
or
Q =
or
Q = 1.256 × 10⁻³ m³/s
