1. An elephant has a mass of 5,500 kg. What is the elephant's weight?
Write equation here:

Answers

Answer:

12125.42 Lbs.

Explanation:

The weight of the elephant is 53,900 N

The given parameters;

mass of the elephant = 5,500 kg

The weight of the elephant is calculated as;

Weight = mg

where;

m is the mass of the elephant

g is acceleration due to gravity = 9.8 m/s²

The weight of the elephant is calculated by substituting the given parameters;

Weight = 5,500 x 9.8 = 53,900 N

Thus, the weight of the elephant is 53,900 N

6. You apply 50 N of force to a lever over a distance of 2 meters. The other end of the lever raises up 1 meter
(a) How weight does the lever lift?
(b) What is the mechanical advantage?

Answers

Answer:

ok this is when we come to calculating the mechanical advantage of a lever. To do this, you divide the distance from the fulcrum, the point at which the lever pivots, to the applied force by the distance from the fulcrum to the resistance force. Using this picture, this means dividing distance b by distance a.

A dolphin can hear sounds with frequencies up to 280 kHz. What is the
speed of sound in water if a wave with this frequency has a wwavelength
of 0.51 cm?

Answers

Answer:

1428  m/s

Explanation:

Given that,

The frequency hear by a dolphin, f = 280 kHz

We need to find the speed of sound in water if a wave with this frequency has a wavelength  of 0.51 cm.

The formula for the speed in terms of wavelength and frequency is given by :

[tex]v=f\lambda\\\\v=280\times 10^3\times 0.51\times 10^{-2}\\\\v=1428\ m/s[/tex]

So, the speed of sound in water is 1428  m/s.

What happens to an object if the sum of the forces acting on it is greater than
zero?

Answers

When more than one force acts upon an object, the vector sum of these forces is the resultant force. When the resultant force on an object is zero, it will remain at rest if it is at rest, or continue to move in a straight line at a constant velocity if it is in motion. ... That is, there is zero acceleration.

C. 9 Hz
D. 20Hz

Answers

Answer:

its B

Explanation:

i just took the test

0.1 Hz the approximate frequency of the wave shown.

What is Frequency?

In physics, frequency is the number of waves that pass a fixed point in a unit of time as well as the number of cycles or vibrations that a body in periodic motion experiences in a unit of time.

After moving through a sequence of situations or locations and then returning to its initial position, a body in periodic motion is said to have experienced one cycle or one vibration. See also basic harmonic motion and angular velocity.

The frequency is 2 per second if the period, or time interval, needed to complete one cycle or vibration is 1/2 second; it is 100 per hour if the duration is 1/100 of an hour.

Therefore, 0.1 Hz the approximate frequency of the wave shown.

Could there ever be a situation where a small sports car could have more inertia than a big bus?​

Answers

There could as smaller objects have more inertia. Mass is a measure of an objects in Harsha. Objects with greater mass have a greater in Inertia yet it’s still maintains the same amount of inertia as usual. It still has the same tendency to resist changes in its state of motion. So yes it is possible that there could ever be a situation where a small sports car would have more inertia than a big bus. :)

what happens to the current across a circuit when the voltage is doubled while the resistance is held back ​

Answers

Since the current is inversely propotional to its resistance, when the voltage is doubled the current will be one-half

The current is directly proportional to the voltage and inversely proportional to the resistance. So doubling or tripling the resistance will cause the current to be one-half or one-third the original value
