Answer:
9.01amp
Explanation:
Power = V^2/R
Given that v = 11volts, P = 99watts
99 = 11^2/R
11×11 = 99R
121= 99R
R = 121/99
R= 1.22ohms
From ohms Law; V = IR
11volts = I × 1.22ohms
I = 11/1.23
I = 9.01 amp
Answer:
<u><em>a. True</em></u>
Explanation:
<em>Vectors are an important part of the language of science, mathematics, and engineering.</em>
Answer: The velocity of the ball is 30.0 m/s
This can be calculated by using the value of acceleration as 10.0 m/s2 in free fall and the given time of 3.0 seconds. To get the
velocity, one will have to multiply the acceleration with the given time and the
quotient would result to 30.0 m/s. Mostly all object regardless of their mass,
fall to earth with the same acceleration in the absence of air resistance and as
the child drops the ball from a window, it gains speed as it falls.
Answer:
An ion is an atom or group of atoms with a positive or negative charge. Ions form when atoms lose or gain electrons to obtain a full outer shell: metal atoms lose electrons to form positively charged ions non-metal atoms gain electrons to form negatively charged ions.

Answer:
Measurements are used to describe quantitatively real-life situations
Explanation:
Measurement refers to the act of assigning a number (with a unit) to a characteristic of an object or an event.
For example: when we want to measure the size of an object, we can use a rule to measure its length, and we assign a number with a unit for that quantity (for example, 5 cm). In this case, we have done a measurement.
Measurements are used by scientists in order to understand the natural worlds. In fact, without measurements it would be impossible to describe phenomena of the real world quantitatively: it would be only possible to describe them qualitatively, and therefore it would not be possible for instance to derive mathematical laws that describe those phenomena.
