Answer:

\boxed {\boxed {\sf 32 \ Newtons}}

Explanation:

We are asked to find the net force on an object. According to Newton's Second Law of Motion, force is the product of mass and acceleration. Therefore, the formula for calculating force is:

F= m \times a

The mass of the object is 8 kilograms and its acceleration is 4 meters per second squared.

  • m= 8 kg
  • a= 4 m/s²

Substitute these values into the formula.

F= 8 \ kg \times 4 \ m/s^2

Multiply.

F= 32 \ kg *m/s^2

Convert the units. 1 kilogram meter per second squared is equal to 1 Newton. So, our answer of 32 kilogram meters per second squared is equal to 32 Newtons.

F= 32 \ N

The net force on the object is <u>32 Newtons.</u>

The 6 strings on a guitar all have about the same length and are stretched with about the same tension.The highest string vibrat
ahrayia [7]

Answer:

B. d(low)=4d(high)

Explanation:

Frequency of a string can be written as;

f = v/2L

Where;

v = sound velocity

L = string length

Frequency can be further expanded to;

f = v/2L = (1/2L)√(T/u) ......1

Where;

m= mass,

u = linear density of string,

T = tension

p = density of string material

A = cross sectional area of string

d = string diameter

u = m/L .......2

m = pAL = p(πd^2)L/4 (since Area = (πd^2)/4)

f = (1/2L)√(T/u) = (1/2L)√(T/(m/L))

f = (1/2L)√(T/((p(πd^2)L/4)/L))

f = (1/2L)√(4T/pπd^2)

f = (1/L)(1/d)√(4T/pπ)

Since the length of the strings are the same, the frequency is inversely proportional to the string diameter.

f ~ 1/d

So, if

4f(low) = f(high)

Then,

d(low) = 4d(high)

A car with a mass of 1500 kg accelerates when the traffic light turns green. If the net force on the car is 3750 newtons, what i
timurjin [86]

Answer:

2.5 ms⁻²

Explanation:

By Newton's 2nd law,

The rate of change of momentum is directly proportional to the unbalance force applied on the object,

By that you can get the equation,

F = ma ⇒ a = F/m

where terms are in usual meaning

a = 3750/1500 = 2.5 ms⁻²
