Answer:
28.6 ohm
Explanation:
there is a 3rd resistor in series. voltage drop across the resistors will be equal to 60v
7*.2+7*.2 +.2x = 60
2.8+.2x = 60
.2x = 57.2
x = 28.6
Answer:
The boat's acceleration are: a= 0.3 m/s² in west direction.
Explanation:
Fm= 4100 N
Fwi= 800 N
Fwa= 1200 N
Fm - Fwi - Fwa= m *a
clearing a:
a= 0.3 m/s²
Answer:
, 
Explanation:
The situation can be modelled by applying the Principle of Angular Momentum Conservation:

The final angular speed is:



The tangential velocities of the wheel and the clay are, respectively:




Answer:
I think d is the answer haha
Answer:
F=1.65 x 10²⁶ N
Explanation:
Given that
Distance ,R= 3.34 x 10¹² m
Mass m₁= 2.78 x 10³⁰ kg
Mass ,m₂= 9.94 x 10³⁰ kg
we know that gravitational force F given as

G=Constant
G=6.67 x 10⁻¹¹ Nm²/kg²
Now by putting the values

F=1.65 x 10²⁶ N
Therefore the force between these two mass will be 1.65 x 10²⁶ N.
