Answer:
An atom that loses a electron is called a cation and has an overall positive charge.
D. Pickup truck because it's heavy and it gained more momentum
Answer:
The speed of the plane relative to the ground is 300.79 km/h.
Explanation:
Given that,
Speed of wind = 75.0 km/hr
Speed of plane relative to the air = 310 km/hr
Suppose, determine the speed of the plane relative to the ground
We need to calculate the angle
Using formula of angle
Where, v'=speed of wind
v= speed of plane
Put the value into the formula
We need to calculate the resultant speed
Using formula of resultant speed
Put the value into the formula
Hence, The speed of the plane relative to the ground is 300.79 km/h.
Answer:
C. The outer ear has to collect the sound waves and lead them to the middle ear.
Explanation:
In the process of hearing, the first thing that happens is that sound waves enter the outer ear through a passage called "auditory canal" that reaches the eardrum.
The movement of the incoming sound waves causes the eardrum to vibrate and transmit these vibrations to three tiny bones of the middle ear.
The current flowing through the lamp is 1.833A
<h3>What is current?</h3>
The current is the stream of charges which flow inside the conductors when connected across the end of voltage.
From the Ohm's law, V =IR
Here, R is the proportionality constant called resistance of the resistor
A lamp with a resistance of 60 Ohms is plugged into a 110-Volt household circuit.
I = V/R
Put the values, we get
I = 110/60
I = 1.833A
Thus, the current flowing through the lamp is 1.833A
