Answer:
The acceleration of the proton is 2.823 x 10¹⁷ m/s²
The acceleration of the electron is 5.175 x 10²⁰ m/s²
Explanation:
Given;
distance between the electron and proton, r = 7 x 10⁻¹⁰ m
mass of proton, = 1.67 x 10⁻²⁷ kg
mass of electron, = 9.11 x 10⁻³¹ kg
The attractive force between the two charges is given by Coulomb's law;
where;
k is Coulomb's constant = 9 x 10⁹ Nm²/c²
Acceleration of proton is given by;
F = ma
Acceleration of the electron is given by;
Answer:
1.4×10⁵ m/s
Explanation:
Applying,
K = mv²/2............. Equation 1
Where K = Energy of the satellite, m = mass of the satellite, v = speed of the satellite.
make v the subject of the equation
v = √(2K/m)............ Equation 2
From the question,
Given: K = 9.8×10⁹ J, m = 1000 g = 1 kg
Substitute these values into equation 2
v = √(2×9.8×10⁹/1)
v = √(1.96×10¹⁰)
v = 1.4×10⁵ m/s
Answer:
this may seem wierd but a hill
Explanation:
a hill if its steep enough and you have wings on a car or something could make you fly depending the weight wind would also help a stop light no a flat road could if you going fast enough wat movement is depending thiers your 4 options hopee you learned something
Based on the data provided, the force that must be applied at the small piston is f = 1500 × 9.81 × 250/A.
<h3>What is the Pascal principle?</h3>
Pascal's principle states that the pressure applied to an enclosedfluid is transmitted undiminished tp every portion of the fluid.
Mathematically:
f/a= F/A
where
- f is the force applied to the small piston
- a is the area of the small piston
- F is the force at the large piston
- A is the area of the large piston
Therefore:
f = Fa/A
Since the area of the large piston is not given
f = 1500 × 9.81 × 250/A
Therefore, the force that must be applied at the small piston is f = 1500 × 9.81 × 250/A.

Answer:
l= 3.002 cm
Explanation:
Given that
n= 70 turns
B= 1.2 T
θ= 15°
I= 1.5 A
τ = 0.0294 N⋅m
Lets take length of sides is l.
We know that
τ = n I A B sin θ
Area of square ,A= l²
Now by putting the value
τ = n I A B sin θ
0.0294 = 70 x 1.5 x l² x 1.2 x sin 15°
l² = 0.000901 m²
l² = 9.01 cm²
l= 3.002 cm
