Using Ohm's Law V = IR
6.0v / 25 = 0.24 A
I = 0.24A

Maksim231197 [3]

Answer:

7808 m/s

Explanation:

Find NE velocity after 60 s  of acceleration in that direction:

  = a t  =  28.4 m/s^2 * 60 s = 1704  m/s

    Vertical component = 1704 sin 45 = 1204.9 m/s

     Horiz component = 1704 cos 45 = 1204.9  m/s

Add the two vertical components

  6510 + 1204.9 = 7714.9 m/s = vertical velocity

Pythagorean theorem to find resultant of vertical and horiz  v's

Vf ^2 = 1204.9^2   + 7714.9^2 0

Vf = 7808. m/s

The magnitude of the momentum of an object is the product of its mass m and speed v. If m = 3 kg and v = 1.5 m/s, what is the ma
Oliga [24]

Answer:

Momentum, p = 5 kg-m/s

Explanation:

The magnitude of the momentum of an object is the product of its mass m and speed v i.e.

p = m v

Mass, m = 3 kg

Velocity, v = 1.5 m/s

So, momentum of this object is given by :

p=3\ kg\times 1.5\ m/s

p = 4.5 kg-m/s

or

p = 5 kg-m/s

So, the magnitude of momentum is 5 kg-m/s. Hence, this is the required solution.

marshall27 [118]

Answer:

C. Copper

Explanation:

F = Force on string

L_0 = Intial length of string

A = Area of string

E = Young's modulus of material

Change in length is given by

\Delta L=\frac{FL_0}{AE}

It can be seen that the change in length is inversely proportional to the Young's modulus of the material.

Here

E_a=0.7\times 10^{11}\ Pa

E_b=0.91\times 10^{11}\ Pa

E_c=1.1\times 10^{11}\ Pa

\\\Rightarrow E_c>E_b>E_a

So, copper will stretch the least.
