Formula\ for\ heat\ energy:\\\\
Q=mCp(T_2-T_1)\\\\
m-mass=0,1kg\\Cp-specific\ heat\ of\ glass=800\frac{J}{kgC^{\circ}}\\T_2=15^{\circ}\\T_1=-45^{\circ}\\\\
Q=0,1*800(15+45)=80*60=4800J\\\\4800J\ is\ required\ to\ heat\ this\ glass.

<span>System B: The amorphous silicon solar modules have an efficiency of 6%. The dimensions of the solar modules amount to 0.5m by 1.0m. The output of each module is 30 Wp. The modules cost 20€ each. The advanage of the amorphous silicon solar modules is that they perform better on cloudy days in which there is no direct sunlight. Installed in the Netherlands, this system gives, on a yearly basis, 10% more output per installed Wp than the multicrystalline silicon modules. </span>
<span>System A: The efficiency of the multicrystalline silicon module amounts to 15%. The dimensions of the solar module are 0.5m by 1.0m. Each module has 75 Wp output. The modules cost 60€ each.

What is the resultant fore acting on a 500g object accelerating 5m/s2
zimovet [89]

2.5N

Explanation:

Given parameters:

Mass of object = 500g

Acceleration = 5m/s²

unknown:

Resultant force = ?

Solution:

According to Newton's second law "the net force on a body or the resultant force is the product of its mass and acceleration".

Resultant or net force = m x  a

where  m is the mass

         a is the acceleration

Now we need to convert the mass to kg

 1000g  = 1kg

 500g  = \frac{500}{1000} = 0.5kg

Therefore;

 Input the parameters:

    Force = 0.5 x 5 = 2.5N

When nuclear fission occurs _____.
Burka [1]
In case of nuclear fission, the heavier nucleus captures the neutron and splits themselves into daughter nucleus or small fragments. The sum of mass of the fragments is less than the original mass. The missing mass is converted into energy according to Einstein's mass-energy equivalence relation.

What is the relashinship between net force and balanced forces
MatroZZZ [7]

Answer: A net force is the overall force on an object when all the individual forces acting on an object are added together. When there is a net force acting on an object, the force is said to be unbalanced. With balanced forces, equal forces are exerted in opposite directions providing a net force of zero
