Answer:
The mass is 16 [g]
Explanation:
We have to remember the formula that defines density, which mentions that the density is equal to mass divided by the volume.
Now we clear the mass:
Answer:
Explanation:
Using the formula : E = mc²
Where m = mass = 6.8 × 10^-6 kg
c = speed of light = 3 ×10^8 m/s
The amount of joules of energy that would be produced equals :
Plugging in our values :
E = mc²
E = (6.8 × 10^-6) kg × (3 ×10^8)²m/s
E = (6.8 × 10^-6) kg × 9 × 10^16 m/s
E = 61.2 × 10^(-6 + 16)
E = 61.2 × 10^10 J
Answer:
(a)
(b)
(c)
(d)
Explanation:
The linear momentum is defined as:
(1)
Where m is the mass and v is the velocity
<em>a.) </em><em>A proton with mass moving with a velocity of . </em>
Replacing those values in equation (1) it is gotten:
So, it has a linear momentum of
<em>b.)</em><em> A 1.6 g bullet moving with a speed of 374m/s to the right.</em>
Notice that in this case it is necessary to express the mass of the bullet in terms of kilograms:
⇒
<em>c.) </em><em>A 8 kg sprinter running with a velocity of 11.8 m/s. </em>
<em>d.) </em><em>Earth () moving with an orbital speed equal to 29700 m/s.</em>
Answer:
<h3>F = 35.84N</h3>
Explanation:
Force = mass * acceleration (Newton's second law of motion)
Given
Mass = 32kg
Get the acceleration using the expression d = 1/2at^2
3.5 = 1/2 (a)2.5^2
3.5 = 3.125a
a = 3.5/3.125
a = 1.12m/s^2
Get the net force;
F = 3.2 * 1.12
F = 35.84N
Hence the net force used to accelerate is 35.84N
When operating a boat faster than idle speed, the operator must stay at least 100 feet from any other boats, people in water, dock or other structures.
<h3>What is speed?</h3>
The speed of any moving object is the ratio of the distance covered and the time taken to cover that distance.
Speed s = distance d / time t
The 100-foot regulation states that No individual will operate any boat or people on water skis, an aquaplane, a surfboard, or any comparable gadget on the waters when a speed more prominent than idle speed.
Thus, when operating a boat faster than idle speed, the operator must stay at least 100 feet from any other boats, people in water, dock or other structures.
