Answer;
<u>= 56.96 mA</u>
Explanation;
From the Ohm's law;
V = IR, where V is the potential difference in volts, I is the electric current in amperes and R is the resistance in ohms.
V = 4.5 volts, R = 79 Ω
Making I the subject of the formula we get;
I =V/R
= 4.5 /79
= 0.05696 A
But, 1 A = 1000 mA
Thus; 0.05696 × 1000
<u>= 56.96 mA</u>
Answer:
H = 5.35 cm
Explanation:
As per energy conservation we know that energy stored in the spring is converted into gravitational potential energy when it is reached at the top
now we have
here we know that
m = 1 kg
k = 105 N/m
x = 0.1 m
now plug in all data in it
now solving for height H we have
Answer:
The images show two different types of Galapagos tortoises that scientists believe descended from the same species. The first type (left) are found on islands that have high vegetation and few grasses. The second type (right) are found on an island that has large amounts of grasses and low-lying shrubs. What explains the type of turtle found on the islands with high vegetation?
Explanation: BA;L
There will be the following forces:
Force of gravity directly down.
The normal force perpendicular to the hill.
The braking force directed uphill.
The frictional force directed uphill.
