Can you please help me with this physics question
erastova [34]

Answer:

See the answers below

Explanation:

We can solve both problems using vector sum.

a)

Let's assume the forces that help the diver dive as positive downward, and the forces that oppose upward, as negative

F_{resultant}=100+30-85+900\\F_{resultant}=845[N]

The drag force is horizontal d this way in the horizontal direction we will only have the drag force that produces the water stream.

F_{drag}=50[N]

b)

Let's assume the forces that propel the rocket upwards as positive and forces like the weight of the rocket and other elements as negative forces.

F_{resultant}=960+7080-7700\\F_{resultant}=340 [kN]

Calculate the height of stairs a 60 kg student would have to run in order to burn off 1 Calorie of food energy, which is the equ
Trava [24]

The height of stairs a 60 kg student would have to run in order to burn off 1 Calorie of food energy will be 7.1 meters.

<h3>What is potential energy?</h3>

The potential energy is due to the virtue of the position and the height. The unit for the potential energy is the joule.

Given data;

Mass of student,m = 60 kg

Energy,E = 4190 J

Height of stairs,h=?

The potential energy is mainly dependent upon the height of the object. The potential energy is found as;

Potential energy = mgh

E=mgh

h=E/mg

h= 4190 J / (60 kg× 9.81  m/s²)

h = 7.1 metre

Hence the height of the stairs will be 7.1 meters.

To learn more about the potential energy, refer to the link;

A current of 1.4 A flows in a conductor for 7.0 s. How much charge passes a given point in the conductor during this time?
bija089 [108]

Answer:

The charge passes a given point in the conductor during this time is 9.8 C.

Explanation:

Given that,

Current = 1.4 A

Time = 7.0 sec

We need to calculate the charge during this time

Charge :

Charge is the product of current and time.

In mathematically form,

Q = i\times t

Where, i = cirrent

t = time

Put the value into the formula

Q =1.4\times7.0

Q=9.8\ C

Hence, The charge passes a given point in the conductor during this time is 9.8 C.
