Answer:
Less
Explanation:
Since acceleration is inversely propotional to mass keeping the force constant, hence more mass will accelerate less and vice versa.
Answer:
2400 kilogram per cubic meter
Explanation:
the density of concrete is a measure of its unit weight.
concrete is a mixture of cement, fine and coarse aggregates, water and sometimes some supplementary materials like fly ash, and various admixtures.
The magnitude of the magnetic field in the region through the current passes is 8×10⁻³ T.
<h3>What is a magnetic field?</h3>
The magnetic field is defined as the field the magnetic materials generate or when an electric charge moves in a field region that generates the magnetic field.
As we know:
F = ilB
F is the magnetic force
i is the current
l is the length
B is the magnitude of the magnetic field
Here F/l = 0.120 N/m
i = 15 A
B = (F/l)(1\i)
B = (0.120)(1/15)
B = 0.120/15
B = 8×10⁻³ T
Thus, the magnitude of the magnetic field in the region through the current passes is 8×10⁻³ T.

Explanation:
7.7 m/s
1st determine you subject slade to you have a mass of 15 kg being subjected to a force of 180N
so.
180N/15kg=180(kg m)/s^2/15kg=12 ms^2
now determine how long u pushed it
d=0.5 A T^2
sutable the known values getting
2.5 m = 0.5 12 ms^2 T^2
2.5m= 0.6 ms^2 T^2
0.41667 s^2=T^2
0.645497224s=T
the velocity multiply the time by the acceleration giving
0.645497224 s 12 ms^2 =7.745966692 ms.
after rounding the 2 significant u get 7.7 ms
Answer:
Chemical potential energy is the energy stored in the chemical bonds of a substance. The various chemicals that make up gasoline contain a large amount of chemical potential energy that is released when the gasoline is burned in a controlled way in the engine of the car. The release of that energy does two things
Explanation:
The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.
