Two charges of magnitude 5nC and -2nC are placed at points (2cm,0,0) and

Answer:

The response to your inquiry is: 15 m/s²

Explanation:

Equation    x = at³ - bt² + ct

a = 4.1 m/s³

b = 2.2 m/s²

c = 1.7 m/s

First we calculate x at t = 4.1 s

x = 4.1(4.1)³ - 2.2(4.1)² + 1.7(4.1)

x = 4.1(68.921) - 2.2(16.81) + 6.97

x = 282.58 - 36.98 + 6.98

x = 252.58 m

Now we calculate speed

v = x/t = 252.58/ 4.1 = 61.6 m/s

Finally

acceleration = v/t = 61.6/4.1 = 15 m/s²

Electromagnetic radiation, commonly called visible light.

A tennis player recovering from an ankle injury, restricted from pivoting, can keep her cardiovascular fitness by using the rowing machine, pedaling on a stationary bike with one leg, or swimming. These exercises do not necessitate directional changes and are safe for her injury.

Answer:

If the net force acting on an object doubles, its acceleration also doubles. Conversely, if the mass is doubled, the acceleration will be halved. If both the net force and mass are doubled, the acceleration remains the same.

Answer:

a) factor

b) factor

c) factor

d) factor

Explanation:

For an oscillating spring-mass system, the time period is expressed as:

where:

represents the frequency of oscillation

signifies the mass linked to the spring

is the spring's stiffness constant

a) If the mass is doubled:

• New mass,

Thus, the new time period:

this leads to factor as per the question.

b) When the stiffness constant is quadrupled, holding other factors constant:

New stiffness constant,

Thus, the new time period:

this results in factor as required.

c) When both mass and stiffness constant are quadrupled:

New stiffness,

New mass,

Thus, the new time period:

which leads to factor as stated in the question.

d) If amplitude is quadrupled, the time period remains unaffected because T does not depend on amplitude as demonstrated by the equation.

Thus, factor
