A 1.5 wire carries a 8 A current potential difference of 89 V is applied . What is the resistance of the wire

S_A_V [24]

We have no idea what the 1.5 means. Fortunately, we don't need it.

Resistance = voltage / current

= (89 v) / (8 A) = 11.125 ohms

An object accelerates downward at a constant rate of 2.00 m/s2 while completely submerged in water. Neglect the viscosity (fluid

Sidana [21]

Answer:

833kg/m³

Explanation:

We have volume as Vm³

Density of this object = dKg/m³

Water density = 1000kg/m³

g = 10m/s²

We calculate FB which is the the buoyant force on object. Calculated as volume of object multiplied by water density

Fb = 1000Vg upwards

W = Vdg

Acceleration = net upwards/m

M = mass

2 = (1000g-gd)/d

2d = 10000 - 10d

2d + 10d = 10000

12d = 10000

d = 833.33kg/m³

Approximately 833kg/m³

The average density of the object is therefore 833kg/m³

If the y component of a vector is 36, and the angle between the vector and the x-axis is 27, what is the magnitude of the vector

statuscvo [17]

Answer:

79.29

Explanation:

Given that,

The y component of a vector, y = 36

The angle between the vector and the x-axis is 27.

We need to find the magnitude of a vector.

Let a and b are x and y component of a vector m. There resultant is R. So,

$R=\sqrt{a^2+b^2}$

Where

$a=c\cos\theta\ \text{and}\ b=c\sin\theta$

We have, b = 36 and θ = 27°

So,

$36=R\sin\theta\\\\R=\dfrac{36}{\sin\theta}\\\\R=\dfrac{36}{\sin(27)}\\R=79.29$

So, the magnitude of the vector is 79.29
