Questions that can be answered by doing the experiment and making observations scientifically:
1). How long will it take to perform the complete experiment ?
2). Will it be daytime or night-time when the experiment begins ?
3). What will be the range of outdoor temperatures during the experiment ?
4). How many times will progress of the experiment be suspended in order to take phone calls ?
Answer:
2.25 N upwards
Explanation:
Answer:
800 N/C to the right
Explanation:
The equation that relates force on a charge, electric field and charge is
where
F is the force acting on the charge
q is the charge
E is the electric field
In this problem, we have
is the electric field
is the charge
Substituting into the formula, we find the force
Concerning the direction:
- The electric field and the force have same directions if the charge is positive
- The electric field and the force have opposite directions if the charge is negative
Here the charge is negative, so the electric field has opposite direction to the force: therefore, it must be upwards.
the answer is 40.5 because you have to multiply the density and volume of the object to get the mass.
Answer:
1747.41 kg
Explanation:
If 1 piculs = 100 gins,
Then 28.9 piculs = (28.9 × 100) gins = 2890 gins.
Also,
If 1 gin = 16 tahils
then 2890 gins =( 16 × 2890 ) = 46240 tahils
Also,
If 1 tahil = 10 chees,
Then 46240 tahils = 46240 × 10 chees = 462400 chees.
Also,
If 1 chee = 10 hoons
Then 462400 chees =( 10 × 462400) hoons = 4624000 hoons.
Also,
If 1 hoon = 0.3779 g,
Then 4624000 hoons = 0.3779 × 4624000 = 1747409.6 g.
The mass in kg that i will declare in the shipping manifest = (1747409.6/100 )kg = 1747.41 kg
