Answer:
water can be used as displacement to calculate the volume of a solid object.
<span> All of the choices were physicists, bu</span>t the answer was Ampere. The discovery that one current-carrying wire exerts a force on a second current-carrying wire was made by Andre-Marie Ampere.
Answer:
1. A proton's magnetic moment arises from a fundamental quantum property called spin, which causes the proton to behave as a tiny bar magnet with a north and a south pole. When placed in an external magnetic field, the proton's spin can either align with the field or flip to orient itself against the field
2. The force can change the direction (velocity) of the proton but not its speed (magnitude).
Answer:
Final speed of the train, v = 168.61 m/s
Explanation:
It is given that,
Acceleration of the train, 
Time taken, t = 3.85 min = 231 s
Initial velocity of the train, u = 4.6 m/s
We need to find the final velocity (v) of the train. It can be calculated using first equation of motion as :
v = 168.61 m/s
So, the final velocity of the train is 168.61 m/s. Hence, this is the required solution.
Answer:
130m
Explanation:
What we know:
- both tables have a mass of 29kg
- the gravitational force (F_g I'll call it) is a 4.24×10⁻¹⁰[N]
- G = 6.67×10⁻¹¹[m³/kg-s²]
- F_g = GMm/R²); where "M" and "m" are the two object's masses and "R" is the distance between them
With that information, all we need to do here is plug in the known values and then isolate "R" to find the distance between the two tables.
F_g = 4.24×10⁻¹⁰ = (6.67×10⁻¹¹)(29)(29)/R²
R = √[(6.67×10⁻¹¹)(29)(29)/4.24×10⁻¹⁰] = 132.2988...m = 130m
