Answer: B. Scientific conclusions are based on empirical evidence, while pseudoscientific conclusions are not.

Explanation:

Scientific conclusions are based on evidences that are obtain through detail experimental process. Thus the claims done by the scientific conclusions are acceptable. But the pseudoscience includes the conclusions which are based beliefs, facts which are not generated after detailed experimental procedure. Thus the claims done by the pesudoscience are not acceptable.

A camcorder has a power rating of 10 watts. If the output voltage from its battery is 3 volts, what current does it use?

Gemiola [76]

The power is calculated using the following rule:
Power = voltage * current
We are given that:
power = 10 watts
voltage = 3 volts

Substitute with the givens in the above equation to get the value of the current as follows:
P = V*I
10 = 3*I
current (I) = 10/3 amperes

You are helping your friend move a new refrigerator into his kitchen. You apply a horizontal force of 275 N in the positive x di

Volgvan

Answer:

f = 347.08 N

Explanation:

The frictional force exerted by the floor on the refrigerator is given as follows:

$f = \mu R = \mu W$

where,

f = frictional force = ?

μ = coefficient of static friction = 0.58

W = Weight of refrigerator = mg

m = mass of refrigerator = 61 kg

g = acceleration due to gravity = 9.81 m/s²

Therefore,

$f = \mu mg\\f = (0.58)(61\ kg)(9.81\ m/s^2)\\$

Answer:

$3 m/s^{2}$

Explanation:

ΣF=ma

The two forces at play are the force applied and the force due to friction. As they are opposing forces set the direction being pushed as the positive in the x direction. the equation you come out with is 60 - 15=(15)A (we know mass to be 15kg). Solve for 3 m/s^2.
