Answer:
10 kg
Explanation:
The question is most likely asking for the mass of the bicycle.
Momentum is the product of an object's mass and velocity. Mathematically:
p = m * v
Where p = momentum
m = mass
v = velocity
Hence, mass is:
m = p / v
From the question:
p = 25 kgm/s
v = 2.5 m/s
Mass is:
m = 25 / 2.5 = 10 kg
The mass of the bicycle is 10 kg.
In case the question requires the Kinetic energy of the bicycle, it can be gotten by using the formula
K. E = ½ * p * v
K. E. = ½ * 25 * 2.5 = 31.25 J
The volume of a solid is stable, the shape of a solid is stable.
The volume of a liquid is stable, the shape of a liquid is not stable.
The volume of a gas is not stable, the shape of a gas is not stable
Answer:
Cuolomb is SI unit of charge
1 e=1.6022E-19 C
1 C = 6.2415E+18 e
Explanation:
Coulomb(C) is the SI unit for measuring electric charge and is given as the product of current and time. To convert Cuolomb to electron, we multiply each cuolomb of charge by 1 C = 6.2415E+18 e while to convert electron into charge, we multiply the electrons by 1e=1.6022E-19 C
Answer:
C. Hot pavement burning your feet
Explanation:
Convection is a type of process where heat travels upwards and cold travels downwards.
Answer:
The time taken for the daredevil to travel the 50 m horizontally is 2.83 s.
Explanation:
Given;
angle of projection, θ = 45°
initial speed of the projectile, u = 25 m/s
horizontal distance traveled by the projectile, x = 50 m
The time taken for the daredevil to travel the 50 m horizontally is calculated as;
where;
is the horizontal component of the velocity = uCosθ
Therefore, the time taken for the daredevil to travel the 50 m horizontally is 2.83 s.
