A constant force = 2.00 n + 3.00 n acts on a 5.00 kg object as it moves in a straight line from the position1 = 1.00 m + 1.00 m
nata0808 [166]

force acting on the object is given as

F = 2.00\hat i + 3.00 \hat j

initial and final positions are given as

r_i = 1.00 \hat i + 1.00\hat j

r_f = 4.00 \hat i - 1.00\hat j

now the displacement is given as

d = r_f - r_i

d = (4.00 - 1.00)\hat i + (-1.00 - 1.00)\hat j

d = 3 \hat i - 2\hat j

now the work done is given as

W = F.d

W = (2.00\hat i + 3.00\hat j).(3\hat i - 2\hat j)

W = 0

so there is no work done

An unknown radioactive element decays with a half life of 0.210 days. What is the decay constant, expressed in 1/microseconds, f
sergeinik [125]

The amount of a radioactive element over time can be written as:

N=N_0e^{-\lambda t}

So, considering that we know the time of its half life, we know how long it takes to get to half the original amount. This is (usint the amount of days in microseconds):

0.5=1*e^{-\lambda *0.21*24*3600*10^6}\Rightarrow0.5=e^{-1.8144*10^{10}*\lambda}ln(0.5)=-1.8144*10^{10}*\lambda\Rightarrow\lambda=\frac{ln(0.5)}{-1.8144*10^{10}}=3.82*10^{-11}

Thus, lambda=3.82*10^(-11)/microseconds

Energy transferred as heat always moves from an object
nata0808 [166]
Well, if we are being technical, yes and the only reason I say yes is because the sun is a hot gas rock. And it gives off UV rays which is heat on earth. So, yes. It does

What happens if both the maximum voltage and current are exceeded and 10W of power must be dissipated?
Aleksandr [31]

Answer:

If both the maximum voltage and current are exceeded  in a resistor, that the point will lie in the thermal breakdown of the resistor.

Explanation:

This indicated that there will be an abundance of free electrons which will be available freely. This abundance of the electrons in a conductor,  will result in the reduction of the overall conductivity. whereas in an insulator or semiconductor this will enhance the overall conductivity.

As the point lies in the thermal breakdown, the Ohm's law is no longer valid and thus no analytical solution can be presented in this regard.
