Answer:

Refractive motion is the impact of a light wave that travels from medium to medium in an angle away from normal, where the direction of light varies. Light is refracted when it crosses the air-to-glass interface and moves slower.

. A 6 ohm resistor is connected to a 15 volt battery.

Sunny_sXe [5.5K]

Answer:

2.5A , 22500 JOULE

Explanation:

Resistance (R)= 6 ohm

Voltage (V) = 15 volt

Current (I) = ?

From ohm's law,

V=IR

15 = 6*I

I = 2.5 A

time(t) = 10min = 600 second

heat energy (Q) = ?

from Joule's law of heating,

Q = I²*R*t

Q = 2.5² *6*600

Q = 22500 Joule

hence, heat energy produced is 22500 joule.

Two equal forces act on two different objects, one of which has a mass ten times as large as the other. The larger object will h

elena-s [515]

Answer:

The larger object will have <u>smaller</u> acceleration that the less massive object.

Explanation:

Generally force is mathematically represented as

$F = ma$

=> $m = \frac{F}{a }$

at constant force we have

$m \ \alpha \ \frac{1}{a}$

So if m is increasing a will be decreasing which means the object with the larger mass will have less acceleration
