Answer:
252J
Explanation:
Given parameters:
Distance = 72m
Force = 3.5N
Unknown:
Work done on the house = ?
Solution:
Work done is the force applied to move a body through a particular distance.
Work done = Force x distance
Now insert the parameters and solve;
Work done = 3.5 x 72 = 252J
It doubles
Momentum= mass * velocity
when velocity doubles
momentum= 2*(velocity* mass)
To determine which object has the greatest acceleration, you would use the formula:
acceleration = (Final Velocity - Initial Velocity) / Time
Just plug-in values for what you have and see which one has the greatest acceleration. If you're given velocity-time graphs, then the one with the steepest slope would have the greatest acceleration.
The best answer would be:
B. Epi pen
Here is more about it:
An epi pen injects epinephrine into the body to counteract the effects of an allergic reaction. Epinephrine helps narrow blood vessels and open up the airways. This can be used for food allergies, insect bites, and some other allergens. It is very effective and immediately works, but it is short-lived, so seeking medical attention after is still needed.
The acceleration of gravity on Moon B is D) 0.25 m/s2
Explanation:
The data listed in the problem are not clear: find them in the table attached.
The acceleration of gravity on a planet is given by the following equation:
where:
is the gravitational constant
M is the mass of the planet
R is the radius of the planet
Here we want to find the acceleration of gravity on the surface of Moon B, which has the following data:
(mass)
(radius)
And substituting into the equation, we find:
