Correct answer choice is :
C) Low ratios of the frequencies of the original and resultant waves indicate discordant waves.
Explanation:
The sound is created when something vibrates. The vibrating body makes the means around it to vibrate. Vibrations in the air are described going longitudinal waves, which we can hear. Sound waves consist of regions of high and low pressure named compressions and rarefactions. The left ventricle will ultimately lose as depolarization opens from the right ventricle, but the stay in conduction effects in a wide QRS system. In the appearance of LBBB, the T wave should be discordant or diverted opposite the final deflection of the QRS system.

Answer: The ice and shel are at the same temperature.
Explanation: Conduction happens when you have two objects at different temperatures touching each other, in this case, the temperature flows from the hot object to the cold one, until the equilibrium is reached (this means that both objects are at the same temperature). So, in order to conduction to happen, we need a difference in temperature and direct contact. So there are two options of the given that can be the answer: "There is no direct contact" In the sentence says that "the ice is placed on the freezer shelf", so we have direct contact between both objects. "The ice and shelf are at the same temperature" Here both objects are inside of the freezer, so we can expect that both of them are at the same temperature, hence, there is no conduction.
Answer:
the correct answer is d
Explanation:
Electrons move from the atoms in the balloon to the atoms in the cloth, causing the cloth to have a negative charge.
B.
Everyday objects do not have electric charges, so neither the balloon nor the cloth can gain or lose electrons.
C.
Electrons move from the atoms in the cloth to the atoms in the balloon, causing the balloon to have a negative charge.
D.
Electrons are shared equally between the atoms of the balloon and the atoms of the cloth, making both electrically neutral.
The speed at which a car can safely navigate a given curve is determined by the equation for centripetal force and the maximum static friction that prevents the car from slipping. Calculating this speed using the given force of static friction (8,127 N), mass of the car (1,423 kg) and the radius of the curve (30 m), we get a result of roughly 22.6 m/s or 81.4 km/h.
The problem involves finding the speed at which a car can safely navigate a highway curve without slipping, given a set radius and maximum force of static friction. This is a physics scenario involving centripetal force and friction. Centripetal force is the net force causing circular motion and static friction is the friction that acts to prevent the car from slipping off the road.
In this scenario, the maximum static friction matches the required centripetal force for a safe curve negotiation. Hence, the equation for centripetal force, Fc = mv²/r, applies here. In this expression, Fc is the centripetal force, m is the mass of the car, v is the velocity or speed, and r is the radius of the curve. Given that Fc = 8,127N, m = 1,423 kg, and r = 30 m, we can rearrange the formula to find v = √(Fc ∗ r / m).
Running the calculation, v = √((8,127 N * 30m) / 1,423 kg), results in a speed limit of roughly 22.6 m/s. However, as speed limits are not posted in meters per second, it is appropriate to convert the speed to kilometers per hour. Multiply the result by (3600 s/h / 1000 m/km) to convert it into km/h which gives a speed limit of about 81.4 km/h.
