jenny measures the outside temperature as 16 degrees celcius,61 degrees Fahrenheit. she observes precipitation falling from the clouds in a solid form.what type of precipitation is jenny most likely observing. A)hail B)rain C)sleet D)snow

Answers

Answer 1
Answer: A.hail is a reasonable answer 
Answer 2
Answer: A. The temperature is too high for snow or sleet to fall, because both need temperatures lower that 32 degrees F. Jennifer observed precipitation falling from the clouds in a SOLID form, meaning rain is out of the question.

PLEASE HELPWhich of the following is an example of a physical property?

Flammability
Reaction with bases
Solubility
Reaction with oxygen

Answers

Answer:

The correct answer is C) Solubility

Explanation:

Final answer:

Solubility is the example of a physical property from the given options, as it can be observed and measured without changing the substance's chemical identity.

Explanation:

The question is asking which of the listed options is an example of a physical property. A physical property is a characteristic of matter that can be observed or measured without changing the substance's chemical identity. Among the choices given - flammability, reaction with bases, solubility, and reaction with oxygen - solubility is a physical property. This is because solubility refers to a substance's ability to dissolve in a solvent, which can be observed without causing a chemical reaction. On the other hand, flammability and reaction with bases or oxygen are chemical properties, as they describe a substance's ability to react and form new substances.

A child drags a 0.398 kg toy dogacross flat ground at constant speed,
with a 4.63 N force at a 63.0° angle.
What is the force of friction on the
toy?
(Hint: You do NOT need to know the
coefficient of friction.)

Answers

The force of friction on the toy is 2.10 N and it acts opposite to the direction of its motion.

What is friction?

A force called friction prevents one solid object from rolling or sliding over another. Although frictional forces, such the traction required to walk without slipping, may be advantageous, they can provide a significant amount of resistance to motion.

Given parameters:

mass of the toy dog: M = 0.398 kg.

Applied force: F = 4.63 N.

Angle of application of force: θ = 63.0°

Hence, horizontal component of applied force = F cosθ

= 4.63 × cos63.0° N

= 2.10 N.

As the child drags a 0.398 kg toy dog across flat ground at constant speed, this component of applied force is nullified by force of friction.

Hence,  the force of friction on the toy is 2.10 N and it acts opposite to the direction of its motion.

Coriolis effect, global winds and continental deflections are all factors that controla. deep currents
c. surface currents
b. wind currents
d. density of currents

Answers

C.surface currents are the answer
Well, at first glance I'd be tempted to say all of them. The C "force" is why weather maps show winds blowing parallel to isobars and thus around centres of high and low pressure. (You'd expect, or at least I would, that air would flow from high to low pressures, not round them ... )

FIND THE WEIGHT OF A 80 KG MAN ON THE SURFACE OF MOON? WHAT SHOULD BE HISS MASS ON THE EARTH AND ON THE MOON? (ge = 9.8 m/s2 ; gm = 1.63 m/s2)pls answer fast

Answers


Weight = (mass) x (acceleration of gravity at the place where the mass is) .

Man's mass = 80 kg

His weight on Earth = (80 kg) x (9.8 m/s²) = 784 newtons (about 176 pounds)

His weight on the Moon = (80 kg) x (1.63 m/s²) = 130.4 newtons (about  29.2 pounds)

His mass is 80 kg.  Mass is the thing about him that doesn't change. 
He has the same mass on the Earth, on the Moon, or anywhere.
