A 3 column table with 5 rows labeled table A. The first column is labeled voltage in volts with entries 1.0, 5.0, 10, 20, 50. Th

e second column is labeled current: calculated in amps with no entries. The last column is labeled current: experimental in amps. According to Ohm’s law, determine the calculated current for these values in Table A. voltage = 5 V, resistance = 20 Ω: A voltage = 20 V, resistance = 20 Ω: A voltage = 50 V, resistance = 20 Ω: A

A uniform plank of length 6.1 m and mass 33 kg rests horizontally on a scaffold, with 1.6 m of the plank hanging over one end of
salantis [7]

Answer:

Explanation:

consider the principle of moment

when a system is in equilibrium, the clockwise moment (torque) about the pivot is equal to the counterclockwise moment ( torque). Since the plank is uniform the weight of the plank act at the middle which = 6.1 m / 2 = 3.05 m

the distance that can support the weight of the man = d

mass of the man = 70

70 × d = 33 × ( 3.05 - 1.6)

d = 47.85 / 60 = 0.798 m, if the man work beyond this point he will fall.

LuckyWell [14K]

Answer:

<h3>given</h3>
  • - x = (-5)

To find - Value of the equation

Solution -

5x + 40

Putting value of x = (-5) in equation

Calculate the momentum of a 2000-kg elephant charging a hunter at a speed of 7.50 m/s . (b) compare the elephant's momentum with
Sergio [31]

(a) The momentum of a moving object is given by:

p=mv

where m is the mass of the object and v is its speed. In this problem, the mass of the elephant is m=2000 kg and its speed is v=7.50 m/s, therefore its momentum is

p=(2000 kg)(7.50 m/s)=15000 kg m/s


(b) We can use the same formula to calculate the momentum of the tranquilizer dart, whose mass is m=0.04 kg and whose speed is v=600 m/s:

p=mv=(0.04 kg)(600 m/s)=24 kg m/s

we see that the elephant's momentum is much larger than the momentum of the dart.


(c) Again, using the same formula, the mass of the hunter is m=90 kg, his speed is v=7.40 m/s, therefore his momentum is

p=mv=(90 kg)(7.40 m/s)=666 kg m/s
