Answer:

Bananas go through a unique process known as negative geotropism. Instead of continuing to grow towards the ground, they start to turn towards the sun. The fruit grows against gravity, giving the banana its familiar curved shape.

In a simple electric circuit, a 110-volt electric heater
Readme [11.4K]

Answer: 55 ohms

Explanation:

Given that,

Voltage of heater (v) = 110-volt

Current drawn by heater (I) = 2.0 amperes

resistance of the heater (r) = ?

Since voltage, current and resistance are involved, apply the formula for ohms law.

Voltage = current x resistance

i.e v = ir

where r = v / i

r = 110 volts / 2.0 A

r = 55 ohms

Thus, the resistance of the heater is 55 ohms

A suitcase is pulled 28 feet along a flat sidewalk with a constant upward force of 80 lb at an angle of 23degrees with the horiz
Elenna [48]

Answer:

2795.3 J

Explanation:

distance, d = 28 feet = 8.53 m

Force, F = 80 lb = 356 N

Angle, θ = 23°

Work = F x d x cos θ

W = 356 x 8.53 x cos 23

W = 2795.3 J

Thus, the work done is 2795.3 J.

An object has a mass of 120 kg on the moon. What is the force of gravity acting on the object on the moon? A. 12.24 N B. 196 N C
Lady_Fox [76]
Correct answer: B
The force of gravity acting on the object on the moon can be found by multiplying its mass by the acceleration due to gravity on the moon. The acceleration due to gravity on the moon is a constant and is approximately 1.63m/s².
120kg×1.63m/s²=195.6kg.m/s²
kg.m/s²=N
<span>The force of gravity acting on the object on the moon would be of approximately 196N.</span>

Compare the magnitude of the electromagnetic and gravitational force between two electrons separated by a distance of 2.00 m. As
Lesechka [4]
First you need to know about two laws, which are:
1) Coulomb's law
2) Newton's law of gravitation

1.
According to Coulomb's law, Electric force between TWO charges is:
F_{e} =  \frac{k*q_{1}*q_{2}}{r^{2}} -- (A)

Where, k = 1/(4*π*epsilon_not) = 9 * 10^{9} \frac{Nm^{2}}{C^{2}}

Both q_{1} and q_{2} = -1.61 x 10^{-19} C
r = Distance between the two charges = 2.00m

Plug-in the above values in (A), you would get:

F_{e} = (9 * 10^{9} ) (1.61 * 10^{-19}  * 1.61 * 10^{-19}) / (2*2)  

F_{e} = 5.83* 10^{-29} N

2.
According to Newton's law of gravitation:
F_{g} =  \frac{Gm_{1}m_{2}}{r^{2}} -- (B)

Where G = Gravitational constant = 6.674 * 10^{-11} m^{2} kg^{-1}s^{-2}

m1 = m2 = Mass of the electron = 9.11 * 10^{-31} kg
r = 2.0 m

Plug-in the above values in (B), you would get:

F_{g} = (6.674 * 10^{-11}) ( 9.11 * 10^{-31}  *  9.11 * 10^{-31}}[/tex]) / (2*2)  

F_{e} = 5.83* 10^{-29} N

F_{e} = 1.38 * 10^{-71} N

Now do Fe over Fg, you would get:
\frac{F_{e}}{F{g}}  = 4.23 * 10^{42}

Ans: So the blanks are:
1) 5.82
2) 1.38
3) 4.23
