Usimov [2.4K]

Answer:

102.2 degrees Fahrenheit

Explanation:

You can use this formula in order to convert from Celsius to Fahrenheit:

(C x 9/5) +32

39 x 9 = 351

351 / 5 = 70.2

70.2 + 32 = 102.2

If a car is moving to the left with constantvelocity, one can conclude thatthere mustbe no forces applied to the car.the netforc

laila [671]

Answer:Net Force is zero

Explanation:

Given

Car is moving to the left with constant velocity i.e. net force on the car is zero

because change in velocity with respect to time is acceleration thus force is also zero because net acceleration is zero

Mathematically

acceleration $=\frac{\Delta v}{\Delta t}$

as velocity is constant therefore $\Delta v=0$

thus a=0 , F=0

The electric field in a region is uniform (constant in space) and given by E-( 148.0 1 -110.03)N/C. An additional charge 10.4 nC

enyata [817]

Answer:

The y-component of the electric force on this charge is $F_y = -1.144\times 10^{-6}\ N.$

Explanation:

Given:

Electric field in the region, $\vec E = (148.0\ \hat i-110.0\ \hat j)\ N/C.$
Charge placed into the region, $q = 10.4\ nC = 10.4\times 10^{-9}\ C.$

where, $\hat i,\ \hat j$ are the unit vectors along the positive x and y axes respectively.

The electric field at a point is defined as the electrostatic force experienced per unit positive test charge, placed at that point, such that,

$\vec E = \dfrac{\vec F}{q}\\\therefore \vec F = q\vec E\\=(10.4\times 10^{-9})\times (148.0\ \hat i-110.0\ \hat j)\\=(1.539\times 10^{-6}\ \hat i-1.144\times 10^{-6}\ \hat j)\ N.$

Thus, the y-component of the electric force on this charge is $F_y = -1.144\times 10^{-6}\ N.$
