Answer:
7213.7kg/m³
Explanation:
Given parameters:
Volume of the metal chunk = 0.131m³
Mass of the metal chunk = 945kg
Unknown:
Density of the metal chunk = ?
Solution :
To solve this problem, density is the mass per unit volume. It is mathematically expressed as;
Density =
So;
Density =
= 7213.7kg/m³
Answer:
B. 45.0 kg
Explanation:
On earth the object has ;
Mass = 45 kg
acceleration = 9.81 m/s²
On Jupiter, acceleration is 24.79 m/s²
The mass of this object on Jupiter will be 45 kg. It will not change. Mass of an object will only change when you remove part of the object from it or add to it another part. The mass is the same on Earth and on Jupiter. However, due to increased acceleration on Jupiter , the weight will change/ increase because;
Weight = mass * acceleration
<u>On Earth </u>
Weight of the object will be : 45 * 9.81 = 441.45 kg
<u>On Jupiter</u>
Weight of the object will be : 45*24.79 =1115.55 kg
harmless, a sheet of paper
Alpha particles do not possess a high amount of energy and are not very ionizing, since they have a high mass. This makes them relatively safer to work with.
The electric field strength will be 0.6252 V/m. It is the strength at which the field is created by charges.
<h3>What is electric file strength?</h3>
The electric field strength is defined as the ratio of electric force and charge.
The electric field strength is found as;

Hence, the electric field strength will be 0.6252 V/m.
